Summary on Grant Application Form |
|
Ever increasing demand for Internet access over wireless networks for applications such as web browsing, interactive and multimedia services has necessitated a need to develop advanced digital radio architectures and algorithms. A major challenge underlying this goal is the development of sic processing algorithms that have the potential to increase data rates and possess immunity to interference and noise in limited bandwidth. A way to achieve higher data rates where only limited spectrum is available is to exploit the spatial characteristics of the propagation environment. Most high i rate services are asymmetrical in the sense that more bandwidth, or throughput, is required in the downlink (base station to mobile terminal) than in uplink (mobile terminal to base station). Therefore, in this project, novel and robust signal processing algorithms will be developed for downlink transmission, and their performance will be analysed. Specifically, space-time block coding (STBC) based algorithms will be proposed for multiple transmit and multiple receive antennas, and robust closed loop feedback schemes will be developed to attain maximum achievable capacity, while imposing minimal complexity at the receiver. Hybrid STBC and transmit beamformer type diversity schemes will also be developed together with efficient channel estimation techniques. The performance will be evaluated using in depth mathematical analysis and simulation studies based upon error statistics such as bit error rate and frame error rate for UMTS.
