| Abstract | In mobile communications, power is a very important factor and nonlinear amplification of power amplifiers cannot be avoided due to their high power efficiency. This article presents the performance of 2 -shift BPSK modulation scheme used in DS/SS/CDMA wireless communications over multipath Rayleigh fading channel and compares the performance with the performance of conventional BPSK CDMA systems. The performance parameters: Out-of-Band power, average Bit Error Rate(BER) and Spectral Efficiency have been evaluated. In order to obtain improved performance on fading channels, a RAKE receiver has been employed. Finally it is shown that 2 shiftBPSK outperforms conventional BPSK in the presence of nonlinear amplification. Keywords— 2 -shift BPSK, DS/SS/CDMA, Soft/Hard-Limiter, Out-of-Band power, Spectral Efficiency, RAKE Receiver. |
