Smart antennas are one of the most promising methods for increasing capacity of mobile radio systems. Research into this subject has grown explosively in the last five years. MIMO systems, which use multiple antennas at both link ends, are able to increase the capacity even further. The tutorial will give a comprehensive overview over all relevant aspects of both smart antenna and MIMO systems. Measurement and modeling of the spatial propagation characteristics, which form the physical basis for any smart antenna system are discussed as well as signal processing algorithms, hardware architectures, experiences from the construction of an actual testbed, and capacity issues.

MIMO Communications with Partial Channel State Information Go >>

Georgios B. Giannakis, University of Minnesota, and Shengli Zhou, University of Connecticut

Adaptive modems relying on channel state information (CSI) that must be perfectly known and regularly updated at the transmitter can boost rates, only when the fading is sufficiently slow. On the other hand, the proliferation of space time (ST) coding research we have witnessed lately, testifies to the efforts put towards the other extreme: non-adaptive (and thus conservative) designs requiring no CSI to be available at the transmitter. As no-CSI leads to robust but pessimistic designs, and perfect-CSI is a utopia for most wireless links, exciting recent research deals with multi-input multi-output (MIMO) multi-antenna systems based on partial CSI, which offers the ``jack of both trades,'' while encompassing the perfect-CSI and no-CSI paradigms. Such systems are the focus of this tutorial.

Joint Physical and Network Layer Optimisation of Wireless Systems: Smart Antennas, Turbo Coding, Space-Time Coding, Adaptive Transceivers and 'all that' for Improved QoS Go >>

Based on three Wiley/IEEE Press monographs authored by the presenter, (http://www-mobile.ecs.soton.ac.uk/comms/Books.htm), this short course provides an insight into the effects of turbo-coded, turbo-equalised and space-time coded adaptive TDMA, CDMA and OFDM transceivers as well as smart antennas and a range of other efficient networking techniques on the achievable teletraffic capacity of adaptive wireless systems. Conventional systems would drop a call in progress if the communications quality falls below the target quality of service and it cannot be improved by handing over to another physical channel. By contrast, the adaptive transceivers considered simply ‘instantaneously drop the throughput, rather than dropping the call’ by reconfiguring themselves in a more robust mode of operation. The tutorial demonstrates that the proposed beam-forming and adaptive transmission techniques may double the expected teletraffic capacity of the system.

Interference Mitigation Techniques
for Wireless Communication Go >>

Over the last few years the subject of interference as a self-contained discipline, has been followed with special attention. The field of communications has experienced an unprecedented expansion and development on theoretical and applied fronts (radio, mobile, fiber, and satellite), and interference presents unavoidable limitations to capacity, efficiency, reliability, and cost of systems. Interference mechanisms must therefore be fully understood for optimal communication systems to be designed. This tutorial seeks to cover all modern tools of interference analysis for wireless communication systems and presents the most relevant ways for reduction and / or cancellation of interference. Fading is also approached as an interference problem. This work will be an essential set of material for graduate students, researchers, practicing engineers and instructors in the general field of wireless communication systems.
