摘要

根据均匀分布信号和字典的匹配跟踪编码器参数计算匹配跟踪失真。然后，利用解析导出的MP失真近似对MP编码器进行优化。仿真结果表明，优化后的MP编码器在非均匀信号和字典分布下也表现出最佳性能

Optimization of Matching Pursuit Encoder Based on Analytical Approximation of Matching Pursuit Distortion

Distortion of matching pursuit is calculated in terms of matching pursuit encoder parameters for uniformly distributed signals and dictionaries. Then, the MP encoder is optimized using the analytically derived approximation for MP distortion. Our simulation results show that this optimized MP encoder exhibits optimum performance for nonuniform signal and dictionary distributions as well
