Abstract

It is most important in design of digital communication systems to receive correct and errorless data at the receiver end with least SNR and bandwidth. The performance of M-ary PSK communication system is analyzed in terms of probability of error considering AWGN channel. The performance is compared for M =4, 8, 16, 32 in MATLAB Simulink environment. It is observed that SNR requirement for a given BER increases as M increases while bandwidth efficiency increases with M. Further M-PSK systems are bandwidth efficient and have large data carrying capacity.
