摘要：

The gradient adaptive step-size least-mean-square (LMS) algorithms [an important family of variable step-size LMS (VSLMS) algorithms] are revisited, We propose a simplification to a class of the studied algorithms and show that this leads to a new class of VSLMS algorithms,vith reduced complexity but with no observable loss in performance.
