In this paper, the authors present a new approach to cancelling echoes, mostly occurrence in today's telecommunication system due to acoustic coupling between loudspeaker and a microphone. The proposed algorithm is a modified VSS-NLMS-UM algorithm the popularity of this algorithm due to solve a conflicting requirement of fast convergence and low misadjustment. Most of the algorithm was design under-modeling scenario the proposed algorithm doesn't require any prior information about acoustic environment. Due to the specific characteristic of this algorithm are equipped with good robustness feature against the near end signal variation and has a low computational complexity and low level data storage.
