This overview is based on the Wiley/IEEE Press monographs “Blogh, Hanzo: Third-Generation Systems and Intelligent Wireless Networking: Smart Antennas and Adaptive Modulation”; “L. Hanzo, et al.: Adaptive Wireless Transceivers: Turbo-Coded, Turbo-Equalised and Space-Time Coded TDMA, CDMA and OFDM systems'”; “L. Hanzo, et al.: Turbo Coding, Turbo Equalisation and Space-Time Coding'” (for sample chapters and full contents please refer to http://www-mobile.ecs.soton.ac.uk). The 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.

This research-oriented presentation considers the joint benefits of both adaptive physical and adaptive network-layer performance enhancement techniques. More specifically, 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 of the near future are expected to simply 'instantaneously drop the throughput, rather than dropping the call' by reconfiguring themselves in a more robust mode of operation. It is demonstrated that the proposed beam-forming and adaptive transmission techniques may double the expected teletraffic capacity of the system, whilst maintaining the same AVERAGE performance as their conventional fixed-mode counterparts.

Whilst this overview is ambitious in terms of providing a research-oriented outlook, potential attendees require only a modest background in wireless communications. Network operators, service providers, managers and researchers embarking on the joint optimisation of the physical and network layer may find the coverage of the presentation beneficial. The participants will receive a set of slides as supporting material.
