基于AP-DE算法动态迭代步长的研究

摘要

为了促进自适应滤波器的滤波性能，建立了一种变步长的基于直接迭代误差AP-DE算法。通过使得权值均方误差下降速度最大，获得了AP-DE算法的优化迭代步长，并分析了所建立算法权值均方误差的统计特性。%Aim to improve the performance of the adaptive filtering,a variable step size Affine Projection Algorithm with Direction Error (AP-DE)is presented in this paper. By setting the weight Mean Square Error (MSE)decreasing the maximum,the optimal step size is obtained for the AP-DE algorithm. Then,under the optimal step size,the statistical weight MSE for the AP-DE algorithm is analyzed.
