| 摘 要： | 自适应滤波理论技术在很多领域有广泛应用,若实际应用中随机信号和噪声有显著的脉冲特性,则Alpha稳定分布能更好地进行描述。文章给出了在分数低阶Alpha稳定分布噪声环境下的一种两步分离自适应算法TSLMP。实验表明,该算法相对以往的LMP算法计算复杂度大大降低,有良好的收敛特性。

| Abstract: | Adaptive filter theory and technology has wide application in many fields.Alpha-stable distribution can better describe the signal and noise,which with the pulse characteristics,in the practical application of the encounter.In this paper,we proposed a new two-step separation of adaptive algorithm (TSLMP) that in the scores of low-end Alpha stable noise environment. Experiments show that the algorithm is relatively past LMP algorithm significantly reduced computational complexity,and a good convergence prope... |
