Abstract

The main objective of this paper is to make a comparison between implementations of Least Mean Square (LMS) and Normalized Least Mean Square (NLMS) algorithms in voice over IP echo cancellation. There are two main points to make this comparison. The first is the computational performance and the second is the voice quality after echo cancellation is done. To perform the algorithms will be simulated using different delays and attenuations of the echo.
