M-ary systems increase the bandwidth efficiency but higher transmission power is required to obtain an acceptable Bit Error Rate (BER). The performance and constellation diagrams of MPSK signals are analyzed. In this study a general theoretical approach is proposed to enhance the performance of MPSK. The probability of bit error is decreased when the signal is transmitted through dual carrier frequencies and dual constellation diagrams to handle the higher data rate to be transmitted for high order MPSK scheme.
