Abstract :
With the growing development of digital communication systems, it has became necessary to ensure the quality of service for real-time transmission of video applications and give users more powerful and efficient services by using better techniques. Digital modulation techniques have various performance characteristics power efficiency, Bandwidth efficiency, Error rate, cost etc. The M-ary Phase Shift Keying and M-ary Quadrature Amplitude Modulation are used in wireless communication to check test the performance of fading channels. In this paper, evaluation of BER is performed under AWGN, Rayleigh and Rician fading channels. Among these channels, Rician has showing better performances a compared to AWGN and Rayleigh channels.
