Abstract
This paper presents a review on linear and non linear Acoustic Echo Cancellation (AEC) based previous research. The results of previous work on Echo Cancellation (EC) and the present research work of variable step size Least Mean Square algorithm is compared with adaptive filters. The performance of digital transmission system and communication network is degraded due to Inter Symbol Interference (ISI) in the linear and non linear AEC. Due to complexity of the loud speaker, amplifier and low quality in non linear AEC are not taken into considerations. The implementation of linear AEC is based on the assumption of linearity. The performance of echo cancellation algorithms are degraded due to nonlinearities in the acoustic path. Therefore non-linear AEC systems are evaluated and reviewed along with linear AEC.
