Tutorial Descriptions

RFIC Technologies for Low Cost Mobile Communications Systems
David Cheskis, Jazz Semiconductor 

Mobile communications systems have evolved in performance and functionality, and today require integrated circuit technologies that can support the low cost requirements of high volume commercial markets. Analog and mixed-signal components that were once discrete ICs in exotic technologies are now being integrated with other system functions using Si-based technologies in System-on-Chip (SoC) or System-in-Package (SiP) approaches.

 This tutorial will describe the latest semiconductor foundry technologies for mobile communications systems and demonstrate the cost savings that can be achieved using system integration approaches. Technologies that will be covered include SiGe BiCMOS, RF CMOS, modular Si technologies and high performance Si-based passive components. These technologies are ideal for mobile communications because they allow the system designer to optimize both the system performance and system cost. The Si CMOS platform provides the flexibility that allows these technologies to be applied in either a SoC or SiP approach. New implementations of these technologies that reduce cost while maintaining the performance advantages will be presented, including design tools and techniques for optimizing system partitioning.

Signal Processing Techniques for Spectrum Sensing and Communication in Cognitive Radio Networks 
Behrouz Farhang-Boroujeny, Univ of Utah

As the vast majority of the available spectral resources have already been licensed, it appears that there is little or no room to add any new services, unless some of the existing licenses are discontinued. On the other hand, studies have shown that vast portions of the licensed spectra are rarely used. This has initiated the idea of cognitive radio (CR), where secondary (i.e., unlicensed) users are allowed to transmit and receive data over portions of spectra when primary (i.e., licensed) users are inactive. This should be done in a way that the secondary users (SUs) are invisible to the primary users (PUs). The FCC Spectrum Policy task force has already set the rules for the operation of CR networks. Standard working groups, e.g., IEEE 802.22, have also been formed and are currently working on relevant documents or have finalized the stnadards. This tutorial addresses a range of signal processing tools that are available for both spectral sensing and communications, in CR settings.

In the past he has worked in the diverse fields of audio signal processing, magnetic and optical recording channels, CDMA and multicarrier communication systems, MIMO communications, and more recently he has been involved with research related to cognitive radio systems. In this area, his team has studies possible applications of various multicarrier techniques, including the conventional OFDM and filterbank based schemes, in the cognitive radio systems. Their study also includes cross-layer issues in CR networks.

Dr. Farhang-Boroujeny has extensively published in the above fields of study, and has been the speaker at numerous conferences and workshops.

Advances in multi-user MIMO techniques
Yong-Hwan Lee, Seoul National University

Extensive use of Internet and huge demand for multi-media services via portable devices require the development of packet-based radio access systems with high transmission efficiency. Advanced radio transmission technologies have recently been proposed to achieve this challenging task. The use of multiple antennas, known as multi-input multi-output (MIMO), is one of key technologies toward this challenge. This tutorial gives a complete overview of various emerging multi-antenna techniques. It includes beamforming, single-user MIMO, multi-user MIMO and opportunistic MIMO techniques. In particular, the opportunistic MIMO techniques are very new ones that can achieve both the diversity and multiplexing gain simultaneously, providing significant performance gain over the previous MIMO techniques. In addition, this tutorial addresses some hot issues related to the realization, including the flexibility of MIMO configuration, estimation of channel state information, feedback signaling burden for the MIMO information and the effect of channel correlation.

This half-day tutorial is intended to provide the audience with a complete overview of recently developed multi-user MIMO techniques for packet-based wireless systems, including beamforming, diversity, multiplexing and hybrid techniques. In addition, the tutorial will also address implementation-related issues which are of major concerns for the deployment.
