Abstract
This article, variable momentum factor to improve performance of momentum LMS is presented. The momentum factor of algorithm is varied according to a gradient decent designed to reduce the square estimation error during each iteration. So this proposed algorithm has high convergence rate and low steady state misadjustment. Simulation results showed good performance of the algorithm in both stationary and nonstationary environments
