In digital communication scheme design, the foremost objective is to receive data as analogous as the data sent from the transmitter. To outlook the system's performance it is essential to examine the system in term of probability of error. This paper emphases on comparative performance analysis of M-ary PSK modulation schemes. The simulation results exhibit that increasing of M results in increase of BER. Error rates of M-ary PSK system versus the Signal-to-Noise Ratio (SNR) are used to assess the performance of M-ary PSK system.
