摘要

提出了一种采用新的自适应步长控制方程的仿射投影自适应算法。变步长(VSS)是一种基于每个时刻均方误差(MSE)最小化的理论最优估计。结果表明，在收敛的早期，收敛速度得到了提高，在最优值附近的误差很小。通过仿真算例验证了该算法增强的性能特点。

An Affine Projection Algorithm with an Adaptive Step-Size Equation

An Affine Projection (AP) adaptive algorithm employing a new adaptive step-size control equation is proposed. The variable step-size (VSS) is an efficient esti mation of a theoretical optimal one based on the minimization of the mean-square error (MSE) at each time instant. As a result, improvement in convergence speed is attained in early stages of convergence with small misadjustment near the optimum. The algorithm enhanced performance characteristics are verified by simulation examples.
