归一化最小均方（LMS）自适应数字滤波，带测试主程序。,Normalized least mean square (LMS) adaptive digital filter with the test main program.

proposes a Verilog implementation of the Normalized Least Mean Square (NLMS) adaptive algorithm, having a variable step size. The envisaged application is the identification of an unknown system. First the convergence of derived LMS algorithm
