DISTORTION CONTROL IN ONBOARD PROCESSOR DESIGN

Abstract

Attention is focused on distortion as an obstacle in achieving design performance goals of onboard processors used in satellite signalling systems. Despreader signal processing loss is expressed analytically as a function of the end-to-end passband differential phase distortion characteristic. Distortion sources are identified and examined for the type and amount of performance degradation. Coping methods are presented. Typical loss values are given graphically for standard reference purposes.
