摘要

针对匹配跟踪(Matching Pursuit)算法以其灵活的自适应性,在数据压缩、信号特征提取、时频分析等领域取得广泛应用.分析常用的时频谱分解方法及其缺点,论述MP算法原理,在其应用瓶颈计算量大的问题上,将遗传算法应用于MP谱分解,较好地解决运算量大的问题.对地震信号的MP谱分析表明,该技术能有效揭示地震信号的时频信息.
Matching Pursuits algorithm has been applied to many fields such as data compression,signal feature extraction,time-frequency analysis because of the flexible self-adaptation.The paper first analyzes the usual method of time-frequency spectrum analysis and their defects,then introduces the principle of matching pursuits algorithm.Because the amount of the computation is very huge,genetic algorithm is used to matching pursuits spectrum analysis,which can decrease the amount of the computation effectively.The result of seismic signal MP analysis demonstrates that MP can reveal time-frequency information of the signal effectively.
