通过FIR滤波器的自适应调整，不断修正其系统函数，使其与未知系统的参数充分逼近，从而使误差最小，达到系统辨识的目的。-Through the adaptive FIR filter, and continuously revise its system function, so that the unknown system parameters with sufficient approximation, so that the smallest error to achieve system

自适应滤波完成系统辨识，估计系统响应函数，现代信号处理相关-Adaptive filter complete system identification, estimation system response function, modern Signal Processing
