摘　　要：为解决传统音乐信号抗干扰方法存在的干扰信号滤除效率低、信号捕获率低问题,提出基于循环谱特征分析的全频段连续音乐信号抗干扰方法。利用聚类算法提取干扰信号特征,搭建含干扰全频段连续音乐信号接收模型,并分析其循环谱特征。通过自适应频移滤波器滤除干扰信号,实现全频段连续音乐信号的抗干扰。实验结果显示,相较于传统方法,提出的全频段连续音乐信号抗干扰方法提升了干扰信号滤除效率与连续音乐信号捕获率,充分说明提出的全频段连续音乐信号抗干扰方法具备更好的抗干扰效果。In order to solve the problems of low filtering efficiency and low signal acquisition rate of traditional music signal anti-interference methods,a full-band continuous music signal anti-interference method based on cyclic spectrum feature analysis is proposed.The feature of interference signal is extracted by clustering algorithm.The reception model of full-band continuous music signal with interference is built,and its cyclic spectrum characteristics are analyzed.The interference signal is filtered by adaptive frequency shift filter to realize the anti-interference of all band continuous music signal.The experiment results show that compared with the traditional methods,the proposed full-band continuous music signal anti-interference method improves the interference signal filtering efficiency and continuous music signal acquisition rate,which fully shows that the proposed full-band continuous music signal anti-interference method has better anti-interference effect.
