Next Generation Wireless Communication System demands for higher data rate and is continuously rising; there is always a need to develop more efficient wireless communication systems. In this paper, the BER performances is shown analytically and by means of simulation for Rayleigh fading multipath channels and AWGN Gaussian channel for M-ARY PSK and M-ARY QAM. The performance of Additive White Gaussian Noise channel with Rayleigh fading in terms of BER is compared. The main focus is to investigate how much improvements of BER is occurred using M-ARY PSK and M-ARY QAM for AWGN channel and Rayleigh fading channel. In order to choose the most suitable modulation, several criteria such as power efficiency, bandwidth efficiency, and bit error rate are used for evaluation. This paper focuses on error performance of phase modulation schemes in different channel conditions and on the method to reduce bit error rates.
