This file include the normalized LMS algorithm and subband LMS algorithm. all of them are in m.file This file can be used to echo noise cancellation, and active noise control

LMS算法和NLMS算法的比较。模拟的是回声消除。但没办法消除回声，只能做有限的处理。-LMS algorithm and NLMS algorithms. Simulate the echo cancellation. But no way to eliminate echo, can do only limited processing.
