Review of methods of Adaptive Noise Cancellation Using LMS and NLMS Algorithms

Deepika, K. K. Saini

Abstract :

The main goal of this paper is noise cancellation using adaptive filter. The noise cancellation is to estimate the noise signal and to subtract it from original input signal plus noise signal and hence to obtain the noise free signal. There is an alternative method called adaptive noise cancellation for estimating a signal which changes continuously like speech and corrupted by an additive noise or interference. The reference input is adaptively filtered and subtracted from the primary input signal to obtain the estimated signal. This paper studies the desired signal corrupted by an additive noise can be recovered by an adaptive noise canceller using adaptive filter and compare the algorithms which are LMS (least mean square) and NLMS (Normalised least mean square) for changing its coefficients according to the change in the signal
