- Abstract
- This paper investigates the average symbol error probability (SEP) performance of the coherent M-ary phase shift keying (M-PSK) system in a situation where the phase error, quadrature error, and I-Q gain mismatch problems take place all concurrently over an additive white Gaussian noise (AWGN) and Nakagami-m fading channel. An analytical expression for the average SEP is derived. Computer simulation results are included based on our analysis in order to examine the overall SEP performance of the M-PSK system for various combinations of the phase error, quadrature error, and I-Q gain mismatch values.
