Wireless System Design in the Frawework of Channel Capacity
- Qitu Keith ZHANG (Principal Investigator / Project Coordinator)Department of Electrical Engineering
DescriptionIn the first part of this project, the design issue will be tackled for single-input-single-output (SISO) multi-user systems over frequency-selective fading channels for wireless communications systems. Coding, interleaving and user separation are conventionally designed separately to meet their respective performance criteria. In this project, they are treated as different aspects of the same entity, and better transceiver structures are searched in a unified framework of channel capacity in terms of spectral efficiency, reliability and system complexity. In the second part, the design issue for wireless systems with multiple antennas and co-channel interferers will be tackled. The capacity of multi-input-multi-output (MIMO) fading channels in a co-channel interference environment, in closed form, is not available in the literature. The difficulty stems from the need to average the channel capacity over random channel matrices for both signal and interferers. Thus a systematic procedure for the determination of channel capacity with co-channel interferers will be derived, whereby the transceiver structure can be optimized.
