摘　　要：本文研究了一种对当输入端进行自适应预测预处理的自适应滤波器。分析和计算机模拟结果表明,自适应预测预处理能有效地抑制在输入端存在的自相关性干扰(对白噪声无效),从而降低了自适应滤波器的误调噪声,改善了自适应滤波器的稳态性能。This paper studies an adaptive filter with adaptive prediction pre—processing in the primary input. Theoretical analysis and computer simulation indicate that the adaptive pre—processing can suppress autocorrelated interferences in the primary input effecti—vely (it can not suppress white interferences). As a result, The misadjustment of the adaptive filter will be lower, and the steady state behavior of the adaptive filter will be improved when the interferences in the primary input is autocorrelated.
