Journal: COMPUTER ENGINEERING AND APPLICATIONS

Keyword:  信号处理稀疏分解匹配跟踪(MP)遗传算法(GA)改进算法;
Abstract: 信号的稀疏表示在信号处理的许多方面有着重要的应用,基于MP的稀疏分解是目前信号稀疏分解的最常用方法,也是几乎所有稀疏分解算法中速度最快的,但其存在的关键问题仍然是计算量十分巨大.基于利用MP(Matching Pursuit)方法实现的信号稀疏分解算法,采用遗传算法(GA)快速寻找MP过程中每一步分解的最佳原子.并针对基本遗传算法存在的未成熟收敛和易陷入局部最优解的问题,提出了对基于GA和MP的信号稀疏分解的一种改进算法,实验结果证实了改进算法的有效性.
