摘要：

This paper presents the performance of space-time block coding based transmit diversity (STTD) in WCDMA on correlated fading channels and on unbalanced transmitted power. Then, based on the performance, transmitter location optimization in indoor environments is considered. Results indicate that the effective diversity order is retained even when high cross correlation exists and power imbalance exists between signals from different antennas. Also, a global optimization a algorithm with the help of a ray tracer can find transmitter locations which are optimal (global optimum) in the sense of power coverage or overall BER in the area of interest.
