AB  - M-ary Phase Shift Key (MPSK) is an essential digital modulation scheme that supports high data rate
and Frequency Division Multiplexing (FDM). 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.
