T01: Backscatter Radio and RFID: Principles and Applications
Gregory D. Durgin, Georgia Tech, USA

Abstract: The technology behind Radiofrequency Identification (RFID) has shown tremendous recent improvements in chip processing, RF chain hardware, and signaling that will enable many future applications in identification, tracking, passive data exchange, sensor telemetry, and last-leg personal area networking. This tutorial will discuss the history, future, and current physical-layer workings of these types of RF systems which are capable of exchanging information with wireless nodes that have little-to-no power source. The first-principles approach in this lecture will help engineers, researchers, and technologists of varying backgrounds understand the technical issues of RF tag communication and how they affect applications.

T02: Game Theory and Resource Allocation in Wireless Communications
Marco Luise and Giacomo Bacci, University of Pisa, Italy

Abstract: The ever-increasing demand for reliable and ubiquitous high-speed data services calls for new challenges in the design of wireless communication networks. In the near future, wireless networks are expected to support a variety of applications with different quality of service (QoS) constraints. In the last two decades, considerable effort has been made to providing efficient schemes to address resource allocation issues, possibly involving cross-layer optimization. Such design and optimization methods are benefiting from the adoption of sophisticated signal processing techniques at large. Recently, game theory has emerged as an effective framework for the design of a wireless network. Traditionally, the main areas of application of game theory have been economics, political science, biology and sociology, but recently, it has also been widely used in telecommunications and wireless communications. This tutorial provides an overview of the relevant applications of game theory in wireless communications, focusing on noncooperative (distributed) techniques. An important feature of the noncooperative approach is the inherent de-centralization of the algorithms, which allows each user to individually choose its own strategy (e.g., power transmit level at the physical layer, bandwidth allocation at the medium access layer, packet forwarding at the network layer) through a simple noncooperative scheme. Distributed (noncooperative) solutions are in general suboptimal with respect to those obtained via a centralized (cooperative) approach, but they are well suited to a many-node network due to their intrinsic scalability and the simplicity of the relative solutions. The complete de-centralization of the resource allocation scheme allows for the total absence of an infrastructure, which is highly desirable to extend game-theoretic techniques to the design of wireless ad hoc networks.

T05: Mobile-to-Mobile Fading Channels
Gordon Stuber, Georgia Tech, USA

Abstract: Mobile-to-mobile (M-to-M) communication channels play an important role in mobile ad-hoc wireless networks, vehicle-to-vehicle communications, advanced relay-based cellular networks, and other applications. The statistical properties of M-to-M fading channels are quite different from conventional fixed-to-mobile cellular land mobile radio channels. M-to-M communication systems are typically equipped with low elevation antennas on both ends of the link, and both the transmitter and receiver are in motion. A solid understanding of M-to-M channels is necessary for designing reliable M-to-M communication systems and networks. This tutorial deals with modeling, analysis, simulation, and measurements of M-to-M fading channels. Both single-input single-output (SISO) and multiple-input and multiple-output (MIMO) M-to-M fading channels are treated in detail. The tutorial first begins with an introduction to the basic concepts of fading channel modeling and statistical characterization of fading channels. We then consider SISO M-to-M channel modeling and analysis, along with deterministic and statistical sum-of-sinusoids-based channel simulators. Afterwards, we will consider 2-D and 3-D MIMO M-to-M channel modeling, analysis, sum-of-sinusoids-based simulation, and model verification based on MIMO M-to-M channel sounding. Both narrow-band and wide-band MIMO M-to-M channels will be considered. The tutorial will be valuable for scientists and engineers, and Ph.D. students currently working in the area of fading channel modeling in general and M-to-M channel modeling in particular. The tutorial will also be valuable for practicing engineers that are developing M-to-M systems and standards.

T06: Baseband Algorithms and Architectures for Cooperative MIMO Systems with Applications to Evolving System Standards
Presenters: Markku Juntti, University of Oulu
Joseph Cavallaro, Rice University
Abstract: The tutorial covers multiple-input multiple-output (MIMO) and cooperative communication based on multiple antennae with an emphasis on the transceiver algorithms, architectures, and implementations. Application examples include the third generation (3G) cellular communication systems, its advanced Long Term Evolution (LTE), Worldwide Interoperability for Microwave Access (WiMAX) systems and evolving International Mobile Telecommunication (IMT) standards beyond those known as IMT-A. The basic concepts MIMO and cooperative communications are reviewed briefly. Sphere detection based detectors for forward error control (FEC) coded communications, linear equalizers and interference cancellation with the soft feedback or turbo principle based receivers are given most emphasis.

T08: High-Definition Location-Awareness
Moe Z. Win and Henk Wymeersch
Massachusetts Institute of Technology, USA

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 even challenging indoor environments. HDLA relies on a combination of ultra-wide bandwidth (UWB) transmission and cooperative peer-to-peer (P2P) algorithms. In this tutorial, we consider cooperative localization in UWB networks from three points of view: fundamental performance bounds, cooperative algorithms, and experimentation. Fundamental bounds can serve as performance benchmarks, and as a tool for network design. Cooperative algorithms achieve drastic performance improvements with respect to traditional non-cooperative localization. In order to harness these benefits, we must consider realistic operational settings. To this end, we have performed extensive measurement campaigns with UWB radios.

T09: Security for 3GPP’s Evolved Packet System - A Fourth Generation System
Günther Horn, Nokia Siemens Networks, Germany
Marc Blommaert, Devoteam Telecom & Media, Belgium
Dan Forsberg, Nokia Corporation, Finland

Abstract: The tutorial focuses on the security for the Evolved Packet System EPS (formerly called “SAE”) as defined by 3GPP , but extends also to other types of mobile systems, such as WiMAX or eHRPD , by showing how these can be connected to the Evolved Packet Core. EPS is of general interest beyond the 3GPP world as it enables the seamless interoperation of heterogeneous access networks, with security providing an important part of the glue. The tutorial will cover the security for the radio access part as well as the core network part in detail. The tutorial will highlight in particular the security innovations in EPS, including cryptographic network separation and forward security in handovers.
