The objective of this study is to analyze the error performance of phase-shift keying data transmission. The analysis takes as the channel model a random phase-shift, a constant or Rayleigh gain, and additive-white-Gaussian noise. The test statistic for the maximum likelihood receiver with post-detection diversity combining is derived and implementations are obtained. Furthermore, the performance of this receiver is analyzed when the channel model contains additional disturbances e.g., varying path delay, inter-symbol interference, etc., although the receiver is no longer optimum. The approach taken in this investigation of m-phase transmission is to derive probabilities involving the choice between two of the m possible transmissions. These probabilities are then related, through geometric arguments, to probabilities involving the choice of one of m transmissions. This technique is useful because probabilities associated with the two-decision problem are relatively easy to compute. Author
