Abstract
The performance analysis of Rayleigh fading in switched selection transmission diversity system which used in transmitting and receiving ends had been studied and simulation results of this system are presented. The MMSE had been used at MS which give best BER. The limitation of using SSTD at MS can be solved by converting two correlated Rayleigh-fading signals into another two independent Rayleigh-fading signals using transformation matrix. Results had been evaluated and show that F= 1 is better than F = J2 /2 which is the elements of the optimum transformation matrix which convert two correlated Rayleigh fading signals into another two independent Rayleigh fading signals. Also, using OFDM system gives better BER than using CD MA system.
