摘要
同道干扰是影响中短波通信质量的主要因素之一。针对此问题,提出一种基于Fast-ICA的干扰消除方法。首先,分析中短波发射机的工作原理和同道干扰的产生机制。其次,介绍Fast-ICA算法的数学模型和优化求解过程。再次,描述基于Fast-ICA的同道干扰消除方法的关键步骤。最后,搭建实验平台,通过对实际测量数据的分析,验证了该方法的有效性。
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.
