Saddle-point approximation for M-ary phase-shift keying with adjacent satellite interference
Abstract
As the geosynchronous orbit for satellite communication becomes increasingly crowded, the effect of adjacent satellite interference is of primary concern. The saddle-point approximation technique for evaluating the error probability of M-ary PSK systems with adjacent satellite interference is described. In comparison with previous methods, this technique has the advantages of both computational simplicity and accuracy. Results include a sample calculation to study the effect of fading on the uplink of a 12/14-GHz quadraphase-shift-keying system with 3-degree satellite spacings and 3-m earth stations.
