Abstract:
The aim of this paper is to investigate the performance of multi-branch Switch and Examine Combining with Post-examining Selection (SECPS) combining schemes. In this system, when no acceptable path is found after examining all paths, the best path among all these unacceptable paths is selected. With such a system, only one receiver is needed for all branches. We evaluate the performance of this system by considering the effects of spacing distance between antenna elements at Base Station (BS) and the maximum Doppler Frequency (fd) on Bit Error Rate (BER) performance under optimum conditions. These effects are not clarified until now on this system. Moreover, simulation results are calculated under Rayleigh fading
