  Abstract

In tins paper, we present the performance analysis of a multi-path searcher operating over Rayleigh fading channels when multiple transmit antennas are employed in the down-link of W -CDMA system. The simulation results for the receiver operating characteristics (ROC) for 1, 2, and 4 transmit antennas are presented to corroborate the theoretical analyses. We also propose a procedure to find the optimum parameters of double-dwell serial searcher according to the number of the multiple transmit antennas Our analyses and simulations indicate that post-detection integration is not necessary when the number of transmit antennas IS more than two Family, we found that increasing transmit diversity order does not necessarily improve the detection performance when the received pilot signal strength is relatively low Therefore, this gives us a practical criterion on increasing transmit diversity order.
