基于可变阶数的集员滤波仿射投影算法
An Affine Projection Algorithm with Variable Order Based on Set-membership Filtering
摘要
Abstract
To solve the confliction between convergence speed and steady-state misadjustment or computational complexity,a new data-selective affine projection （AP） algorithm is proposed. The algorithm which is called affine projection algorithm with variable order or data-reuse factor based on set-membership filtering （VDRF-SM-AP） generalizes the ideas of the conventional set-membership affine -projection （SM-AP） algorithm to include a variable data-reuse factor. By utilizing the information provided by step size,the data-reuse factor can be automatically adjusted. At the beginning of the algorithm a large data-reuse factor is achieved while a small one is achieved after the algorithm has converged. Simulations show that a significant reduction in the overall complexity can be obtained with the pro- posed algorithm as eompared with the conventional SM-AP algorithm. In addition,the proposed algorithm retains the fast convergence of the conventional SM-AP algorithm,but obtains the lower steady-state misadjustment.关键词
