An Investigation of the Effects of the Error Rate of Multiple Phase-Shift-Keyed Signals Through a Hard Limiter

This paper describes an investigation of channel spacing for multiple biphase-shift-keyed (BPSK) signals accessing a hard-limiter satellite. The effects of intermodulation and modulation spectrum interference on the bit error rate of the active channels were considered. Results and conclusions of experimental errorrate data are presented for various channel spacing arrangements. Of major significance is the formation of rules for the spacing of active channels when six or more BPSK signals are accessing the hard limiter.
