Abstract
The presence of an in-band CW interference can seriously degrade the performance of a telemetry system. Degradation effects for a phase-shift keying (PSK) system can be found in Refs. 1 and 2. The telemetry system employed for deep-space communications is a binary phase-shift keying system (BPSK) with squarewave subcarriers. The use of squarewave subcarriers makes the system less sensitive to in-band interference than a system using sinusoidal subcarriers. A model that allows one to predict the telemetry degradation for the deep-space telemetry system is presented in this article, backed with experimental data.
