Spreading and power control for multiple antenna transmit diversity

This thesis proposes a new transmission scheme for multiple antenna transmission at the base station of a wireless cellular system. We develop our new scheme in a wideband CDMA framework using multiple phases of Gold codes for spreading on different antennas. We evaluate the performance of this scheme and show that it performs well for a wide range of SNR values. We illustrate a strategy for using channel coding along with the new scheme. Unlike most other schemes, we motivate the need to use feedback information from the mobile to do joint power control on the multiple antennas. Our throughput analysis reveals a surprising result; in the context of our problem setting, one bit feedback, indicating which antenna is better, does not give large gains.
