Abstract

Currently, the subcarrier on the satellite communication wireless link has uncertain signal number and bandwidth and non-overlapped frequency spectra of mixed signals, and thus can hardly be separated and identified. Through analysis, a simple and effective estimation algorithm for subcarrier frequency was proposed and the code rate was estimated based on the instantaneous characteristics of the modulated signal. Results show that, using the proposed adaptive separation and recognition method, multiple signals can be effectively separated from the mixed signal, with high precision and strong noise immunity. Moreover, after partition, each subcarrier can be separated by the filter for modulation. The method is characterized by simple principle and ease of implementation.
