TU01: Order Statistics in Wireless Communications: Diversity, Adaptation and Scheduling (Cancelled)

• Wednesday, 15 August • 8:30 – 12:00 • Room: 5
• Instructor: Hong-Chuan Yang (University of Victoria)
• Abstract:
  In this tutorial, we systematically present some new order statistics results and illustrate their applications in wireless system analysis. We first summarize the basics of digital wireless communications over fading channels, which provides the necessary background. Then, the statistical results, more specifically the conventional and new results on the distribution functions of random variables involving order statistics, are presented. After that, we discuss the applications of these results in the analysis and design of several wireless technologies that are essential to future generation wireless systems, including advanced diversity combining techniques, joint adaptive modulation and diversity combining, and multiuser parallel scheduling in wide-band code division multiple access (WCDMA) and multiuser MIMO systems. We strive to achieve an ideal balance between theory and practice. Special emphasis will be placed on the accurate quantification of the performance versus complexity tradeoff throughout the presentation.

TU02: Spectrum and Energy Efficient Heterogeneous Wireless Networks

• Wednesday, 15 August • 8:30 – 12:00 • Room: 6
• Instructor: Rose Qingyang Hu (Utah State University)
• Abstract:
  The proliferation of new applications, e.g., mobile TV, Internet gaming, large file transfer, and the development of user terminals, e.g., smart phones, notebooks, etc., has dramatically increased user traffic and network load. As the spectral efficiency of a point-to-point link in cellular networks approaches its theoretical limits, there is a need for increase in the node density to further improve network capacity and coverage to address the ever increasing traffic demand. Furthermore, the fast growing data traffic and dramatic expansion of network infrastructures will inevitably trigger tremendous escalation of energy demand and energy consumption in wireless networks, which will directly result in the increase of greenhouse gas emission and poses ever increasing threats to the environmental protection and sustainable development. Green evolution has become another urgent need for wireless networks today. The wireless network research should meet the challenges raised by the high demand of both wireless traffic and energy consumption. This tutorial discussed the need for such an alternative strategy, where low power nodes are overlaid within a macro network, creating a wireless Heterogeneous Network (HetNet). In this tutorial we explore a broad scope of technical areas that are under investigation in the context of HetNets. These areas include node/client cooperation, interference management, mobility, green radio, applications and services. This tutorial shall provide deep insights into the motivations and technology enablers for this emerging area as well as the Hetnet development and deployment status in China. The target audience of this tutorial will include people from academia and industry who are interested in research, design, operation, and management of future generation wireless networks and HetNets.

TU03: Bit-Interleaved Coded Modulation: Fundamentals, Analysis, and Design (Cancelled)

• Wednesday, 15 August • 14:00 – 17:30 • Room: 5
• Instructor: Leszek Szczecinski (INRS-EMT) and Alex Alvarado (University of Cambridge)
• Abstract:
  Bit-interleaved coded modulation (BICM) is nowadays the most popular transmission scheme for fading and non-fading channels. BICM has been adopted in commercial systems such as wireless and wired broadband access networks, 3G and 4G telephony, and digital video broadcasting, imposing itself as the de facto standard for current wireless telecommunications systems. Moreover, BICM will very likely be the basis for future communication standards, and therefore, its understanding becomes crucial.
  At first glance, BICM appears to be a very simple transmission scheme. However, a careful analysis reveals intriguing properties and shows many optimization opportunities. In this tutorial, we will provide a simple and comprehensive overview of BICM, and we will lead the audience through the concepts underlying BICM systems. We will explain BICM principles and also explain why BICM became a de facto standard in wireless industry.
  This tutorial is divided into parts which are, to a great extent, self-contained. This allows the participants to focus on the elements that are the most relevant to their particular interests and activities. To simplify the concepts, the tutorial includes simple examples and case-studies. The main focus is on the understanding how to characterize and exploit the non-linear signal processing involved in the basic building blocks of BICM.
  We start by presenting information-theoretic aspects of BICM transmission and analyzing its optimization parameters. Next, we will show the tools that can be used to efficiently analyze and design BICM transceivers. BICM with iterative decoding will be further presented and discussed. We will conclude by showing how the performance of BICM can be improved if the interleaver and the code are properly (jointly) designed.

TU04: Convex Optimization of Cognitive Radio Networks

• Wednesday, 15 August • 14:00 – 17:30 • Room: 6
• Instructor: Chee Wei Tan (City University of Hong Kong)
• Abstract:
  It has been recognized that the radio spectrum is vastly underutilized, and an exciting paradigm has emerged that applies powerful aspects of optimization theory to the design and analysis of networks to efficiently utilize spectrum: Cognitive Radio Networks. Dynamic spectrum sensing via cognitive radio brings forth new intellectual and practical considerations.
  An optimization-theoretic approach has three distinctive characters. First, it unifies disparate problems and algorithms in wireless communication and networking and enables optimization theory to be applied to cross-layer design from the physical layer to networking issues. Second, the watershed between efficiently solvable optimization problems and intractable ones has been recognized as convexity (instead of linearity as previously believed) thus opening up possibilities on nonlinear and nonconvex problems in cognitive radio network design. Third, some of the new theoretical insights and tools are already being put into practice. These accomplishments have resulted in a keen interest from both academia and industry in systematically learning the new tools within the context of cognitive radio networks. This tutorial will provide a comprehensive treatment of recent results on convex optimization of cognitive radio networks.
