N2 - To address the problem of Multi-channel Interference severely affecting the signal Capture of Low-orbit Internet constellation TT & C Transponder in the Satellite Unified Spread Spectrum Measurement and Control System, this article delves into the conditions for generating Multi-channel (Cross-correlation) Interference and the impact of Multi-channel Interference on receiver capture performance from a theoretical perspective, and carries out simulation verification analysis. The simulation results show that several factors, such as Correlation characteristics of the Pseudo-random sequence, Doppler Frequency, Power of Multi-channel Interference, Modulation information data changes, the Relative Doppler frequency Difference between the Multi-channel signal and the useful signal, as well as the Coherent Integration Time Interval, determine the Strength of Multi-channel Interference. Under certain conditions, Multi-channel Interference severely affects receiver capture performance.
