Analysis of Effectiveness of Methods of Protection against Interference Emission from Stationary Plasma Thrusters in Deep-Space Communication Systems
2025
Overview
The paper presents results of comparative analysis of the effectiveness of methods used to compensate pulsed interference emission from stationary plasma thrusters in deep-space communication systems. Algorithms of the quadrature pulse interference limiter and quadrature pulse interference suppressor are considered, as well as the methods of blind signal separation using the analysis of independent components. Simulation modeling for digital radio channel Earth–spacecraft with binary phase shift keying (BPSK and 8PSK) was carried out taking into consideration the train pulsed structure of interference emission from stationary plasma thrusters. The influence of the relative time and phase delays in receive channels on the efficiency of blind signal separation algorithms is analyzed. It is shown that the blind signal separation methods, should the conditions for their applicability be met, provide higher level of pulsed interference suppression if compared to the conventional algorithms, especially at high values of interference-to-signal ratio.
