T1: Cooperative Wireless Communications

Presenter:

Prof. Lajos Hanzo, Univ. of Southampton, UK

Date:

Sunday 23 May 2010 - 09:00-12:20 (w/ coffee break)

Abstract:

In the early days of wireless communications the research community used to view multipath-induced dispersion as an undesirable propagation phenomenon, which could only be combated with the aid of complex channel equalizers. The longer the Channel Impulse Response (CIR) was, the more complex the channel equalizer became. However, provided that the complexity of a sufficiently high-memory channel equalizer was affordable, the receiver could benefit from the fact that the individual propagation paths faded independently. To elaborate a little further, even if one of the paths was experiencing a high attenuation, there was a good chance that some of the other paths were not, which led to a potential diversity gain. However, if the channel does not exhibit several independently fading paths, techniques of artificially inducing diversity may have to be sought. A simple option is to employ a higher direct-sequence spreading factor, which results in a higher number of resolvable multipath components and hence in an increased diversity gain. Naturally, this is only possible if either the available bandwidth may be extended according to the spreading factor or the achievable bitrate is reduced by the same factor. A whole host of classic diversity combining techniques may be invoked then for recovering the original signal. An alternative technique of providing multiple independently faded replicas of the transmitted signal is to employ relaying, distributed space-time coding or some other cooperation-aided procedure, which is the subject of this course. One could also view the benefits of decode-and-forward based relaying as receiving and then flawlessly regenerating and retransmitting the original transmitted signal from a relay - provided of course that the relay succeeded in error-freely detecting the original transmitted signal. This course reviews the current state-of-the-art and proposes a number of novel relaying and cooperation techniques. An important related issue is the availability or the absence accurate channel information, which leads to the concept of coherent versus non-coherent detection at the relays and at the destination. Similarly, the related initial synchronization issues also have to be considered. Naturally, when using hard-decisions in the transmission chain, we discard valuable soft-information, which results in an eroded performance, albeit also reduces the complexity imposed. Hence the hard- versus soft-decoding performance trade-off will also be explored in the course, along with the benefits of interleaved random space-time coding invoked for multi-source cooperation.

Sunday 23 May 2010 - 09:00-12:20 (w/ coffee break)

Abstract:

Next general broadband wireless technologies will bring to reality the dream of accessing high speed data, voice and streaming media wirelessly from anywhere. This tutorial presents the physical layer of two major 4G wireless broadband technologies: 3GPP long-term evolution (LTE, and LTE-Advanced) and WiMax (IEEE 802.16e and 16m). Considering IMT-Advanced technical requirements for 4G technologies, the design goals of both of these technologies are first presented. Then major components and functions of the physical layer of each technology are presented including: multiple access scheme, frame structure, various permutations, various reference signals, ranging, network entry procedures, sounding, adaptive coding and modulation schemes, multiple-antenna and multi-user techniques. Throughout this tutorial, particular attention will be given to differentiating features of each technology. Due to inseparable role of antennas array techniques in wireless broadband communications, particular emphasis will be given to numerous open- and closed-loop MIMO modes, downlink and uplink multi-user MIMO schemes, downlink MIMO channel-quality reporting modes, and usefulness of each of the MIMO techniques in various practical scenarios. Furthermore, research areas where engineers and researchers could contribute new and more efficient algorithms are introduced to participants, particularly from the perspective of complexity, power and bandwidth practical constraints. Finally, the role of 4G technologies in developing countries is reviewed, particularly in providing reliable infrastructure where various sectors such as education, business, disaster recovery planning etc would benefit significantly.

Sunday 23 May 2010 - 09:00-12:20 (w/ coffee break)

Abstract:

The tutorial is to examine issues associated with the successful building and deployment of an efficient and reliable locality aware peer assisted content delivery solution. We start by examining some popular P2P applications, such as BitTorrent, Skype and PPLive. The study of these P2P applications helps us to understand the design principles of P2P applications in general. We then investigate the existing Internet backbone components, such as the data centers, the CDN providers, and the Internet architecture. We will see how a P2P network may effectively compliment the data centers and CDN providers. Finally, we examine a number of tools for building an efficient and reliable P2P application, such as the overlay network, the scheduling algorithm, the erasure resilient coding, and NAT/firewall traversal, P2P economy, security issues, monitoring and debugging utilities in P2P application.

T6: High-Definition Location-Awareness

Presenters:

Prof. Moe Win, MIT, USA

Prof. Henk Wymeersch, MIT, USA

Date:

Sunday 23 May 2010 - 14:00-17:20 (w/ coffee break)

Abstract:

The availability of positional information is of vital importance in many commercial and military applications, including asset tracking, search-and-rescue operations, and personal navigation. The coming years will see the emergence of high-definition location-awareness (HDLA) with sub-meter accuracy and minimal infrastructure requirements, operational in challenging indoor environments. We will first cover four basic components of traditional positioning: ranging techniques (e.g., time-of-arrival, time-difference-of-arrival); positioning algorithms (e.g., least-squares, maximum likelihood); performance bounds (Cramer-Rao bounds); and practical positioning systems (including GPS and WiFi positioning). Secondly, we will discuss the limitations of traditional positioning, and move on to the key enablers for HDLA: wideband transmission and cooperative processing. In the context of HDLA, we will cover fundamental performance bounds, cooperative algorithms, and experimentation. Fundamental bounds serve as performance benchmarks, and as a tool for network design. Cooperative algorithms are a way to achieve drastic performance improvements with respect to traditional non-cooperative positioning. In order to harness these benefits, we must consider realistic operational settings. To this end, we have performed extensive measurement campaigns with UWB radios, the outcomes of which will be detailed during this tutorial.

Dr. Zhi Tian, Michigan Tech University, USA

Prof. Georgios Giannakis, University of Minnesota, USA

Abstract:

Recent advances in Compressive Sensing have demonstrated that signals which are sparse in a certain domain can afford sub-Nyquist sampling via random projections and reliable reconstruction via computationally feasible algorithms. Meanwhile, high-dimensional sparse signals can be recovered from measurements collected from reduced dimension based on the compressed sensing principle. The appealing reduction in signal acquisition and storage costs has spawned a range of new applications in signal processing for communications. This tutorial offers an introduction to the basic theory, algorithms and applications of compressive sensing and sparse signal recovery relevant to wireless communications.

Abstract:

Game theory provides a rich set of mathematical tools to model and analyze cognitive radio systems where the cognitive radio entities have to make decisions on dynamic spectrum access which have possibly conflicting consequences. An intensive (but friendly) introduction to the various game theory models, their fundamental concepts and properties, and their applications in designing dynamic spectrum access protocols for CRNs will be provided. Game theory models for power control, bandwidth allocation/sharing and routing will be illustrated. Important game models from microeconomic theory as well as the theory of auctions, which can be used for spectrum management and pricing in CRNs, will be presented.

T9: Statistical Delay-QoS Provisioning in Wireless Networks: Effective Capacity and QoS-Driven Resource Allocations

Presenter:

Dr. Xi Zhang, Texas A&M University, USA

Date:

Sunday 23 May 2010 - 14:00-17:20 (w/ coffee break)

Abstract:

Based on the speakerÂ¿s extensive and recent research and the previous existing work in the area, this talk presents a comprehensive tutorial on the statistical delay-QoS guarantees in wireless networks by using the effective capacity/bandwidth theories, and addresses the methodologies of cross-layer modeling and optimization based QoS-driven resource allocations. Specifically, we start with a comprehensive overview on the theory of statistical QoS guarantees built on the Large Deviation Principle. Describing the statistical QoS guarantee techniques, we introduce the dual principle between the effective capacity and effective bandwidth, which characterize the wireless-channel capability and the traffic loads as functions of the delay-QoS, respectively. Using the effective capacity as the layer-interfacing tool, we review the cross-layer modeling and the optimized QoS-driven resource allocation schemes for several types of wireless-communications scenarios. Finally, we summarize this tutorial and discuss the potential research directions in the future within these areas.

Meanwhile, researchers have designed new algorithms, routing protocols, and published results from simulation studies. This tutorial will provide a broad understanding of the current state-of-the-art of vehicular networking.

T13: Aspects of Multiuser MIMO-Principles and Standardization in LTE-Advanced

Presenters:

Prof. Gerhard Bauch, UniversitÃ¤t der Bundeswehr Munich, Germany

Prof. Guido Dietl, DOCOMO Euro-Labs, Germany

Date:

Thursday 27 May 2010 - 09:00-12:20 (w/ coffee break)

Abstract:

The tutorial gives both an introduction to the theoretical basis of multi-user (MU)-MIMO as well as to practical problems and solutions which have the potential to make their way into standards. 3GPP-LTE and LTE-Advanced will be used as exemplary framework. Advanced MIMO will be demonstrated to be an indispensible ingredient in order to meet the performance targets for IMT-Advanced even under perfect conditions. The potential benefits of MU-MIMO over SU-MIMO as well as the MIMO modes in LTE will be explained. The relatively poor performance of the LTE MU-MIMO scheme will be demonstrated and motivate to look for better MU-MIMO solutions. Information theoretic limits and non-linear MU-MIMO algorithms which aim at performance close to those limits will be explained. Finally, we will consider linear MU-MIMO schemes and will show that linear schemes can achieve performance reasonably close to capacity approaching non-linear schemes while having significantly lower complexity. We will particularly focus on limited feedback schemes including precoder or channel vector quantization codebook design.

Abstract:

A large portion of radio spectrum around 60GHz has been very attractive for a while, but it pose many challenges in realizing 60 Ghz wireless systems in a cost-effective manner. Recent advances in RF front-end technologies lead to low-cost electronics at 60 Ghz, and receive a lot. of attentions from both academia and industry. In this tutorial, we will discuss multi-gigabit 60 GHz wireless systems from various aspects, including the industry standardizations (IEEE 802.15.3c, WirelessHD, and ECMA), and the design issues for baseband and radio systems at 60 GHz. In the first part of this tutorial, we will discuss three RF system architectures, including zero-IF, low-IF, and super-heterodyne, link budget analysis, and the impacts of RF impairments on the performance of 60 GHz wireless systems. We will also introduce antenna beamforming technology, which is a key to point-to-point applications at 60 GHz wireless systems. In the second part of this tutorial, we focus on the baseband design issues for 60 GHz wireless systems. We first discuss propagation characteristics, channel modeling and measurements at 60 GHz in both line-of-sight (LOS) and nonline-of-sight (NLOS) propagation environments. Next,we compare orthogonal frequency division multiplexing (OFDM) and single-carrier (SC) transmission technologies at 60 GHz in terms of complexity and performance. Then, we address the challenges in designing baseband algorithms at 60 GHz, including channel estimation, synchronization, channel equalization, and signal detection. We will also discuss how antenna array technologies can simplify the baseband algorithm design at 60 GHz. In the end, we will highlight the opportunities and challenges in developing the multi-gigabit wireless systems at 60 GHz.

T16: Stochastic Geometry and Random Graphs for the Analysis and Design of Wireless Networks

Presenter:

Dr. Martin Haenggi, University of Notre Dame, USA

Date:

Thursday 27 May 2010 - 14:00-17:20 (w/ coffee break)

Abstract:

Confronted with the difficulties of analyzing large wireless networks such as cellular, ad hoc, and sensor networks, researchers have realized that the mathematical techniques used need to incorporate and explicitly model the network geometry. As a consequence, stochastic geometry and the theory of random geometric graphs have emerged as essential tools in the analysis and design of large wireless systems. In the last decade, these techniques have led to important results and insights on the connectivity, capacity, and fundamental limits of wireless networks, and the coverage of sensor networks. Specifically, point process theory, percolation theory, and probabilistic combinatorics were instrumental in recent breakthroughs, and we strongly believe their importance will increase further and will be crucial in the design of future cellular systems and ad hoc networks. We feel it is essential to educate current and future researchers in these techniques. In short, stochastic geometry and random graphs for the analysis and design of wireless networks, is an emerging hot topic that has both theoretical and practical significance. The objectives of this tutorial are to demonstrate the strengths and the beauty of these analytical tools and to put the tutorial attendee in the position to understand technical articles in this area and to self-educate them more deeply so that they can themselves make contributions.
