Abstract
Co-channel interference is one of the main factors affecting the quality of medium and short wave communication.To solve this problem,a method of interference elimination based on Fast-ICA is proposed in this paper.This paper analyzes the working principle of medium and short wave transmitter and the generation mechanism of co-channel interference,introduces the mathematical model and optimization process of Fast-ICA algorithm,describes the key steps of the co-channel interference elimination method based on Fast-ICA,and finally sets up an experimental platform to analyze the measured results.
