Abstract

A model of direct-sequence spread-spectrum carriers accessing a limiting satellite repeater in the presence of strong interference (tone jamming, other users, and Gaussian noise) is presented. A simplified phasor analysis is used to obtain a strict upper bound on system bit error rate. Comparisons are made of the bit error rate for a limiting repeater system and that obtained for a linear repeater system. For a quadriphase spreading code, the upper bound on the average degradation due to the limiting repeater was approximately 4 dB for an error probability of 10/sup -4/.<>
