Performance Analysis of MDPSK and Equiprobable Correlated Binary Signals

this paper,we present closed-form expressions for the exact average symbol error rate(SER) of combined transmit antenna selection(SC)/ receive maximum ratio combining(MRC) with a general class of M-ary modulations(including M-ary differential phase shift keying,noncoherent detection of equiprobable correlated binary signals,and differential quaternary phase shift keying with Gray coding) over Nakagami fading channels.We investigate the effects of channel fading parameter and the number of transmit and receive antennas on the average SER performance of the above various modulation schemes.Numerical results show that the average SER performance of the combined SC/MRC system can improve with increased product of the number of transmit and receive antennas at high signal-to-noise ratio regions when the total number of transmit and receive antennas is fixed,and that the average SER performance of the combined SC/MRC system can improve with increased fading parameter.
