Performance Analysis of Two Closed Loop Antenna Transmit Diversity Modes for WCDMA

DU Zhi min,XUE Qiang,ZHOU Sheng,WU Wei ling (School of Information Eng.,Beijing University of Posts & Tele.,Beijing 100876,China)  
Simple close form expressions for different diversity methods′ theoretical performance are derived in this paper under the assumption of perfect channel estimation.When channel estimation error should be considered,we can simply substitute the original E s/N o in each expression with a new effective value.Simulation results validate the correction of this method.Based on the performance bounds determined by these new expressions,we study the performance of the two closed loop modes with different Doppler frequency and different processing methods at the UE (user equipment).
