As data rate demands on existing satellite systems increase, the need to evaluate more bandwidth efficient modulation schemes such as M-ary phase Shift Keying (MPSK) becomes important. However, the unavailability of higher order modems operational at higher data rates and the construction of such a complex device for testing purposes can make evaluation difficult. In support of NASA grant NAG 5-1491, New Mexico State University has developed a method of evaluating the performance of 8PSK in a satellite channel using a QPSK signal set. This paper will discuss this technique and will generalize the results to the use of any (M/2)PSK signal set to evaluate MPSK modulation. Verification by both computer simulation and hardware implementation will also be discussed.
