Abstract
The scope of this paper is interference cancellation which is concerned with removal of noise superposed on speech signal. Interference cancelling makes use of an auxiliary or reference input derived from one or more sensor located in noise field where the signal is undetectable. This input is filtered from primary input containing both signal and interference. Adaptive filtering which are able to lock-in on the frequency of interference and to tracks its changes is required. In order to achieve this, a reference signal should be available which is strongly correlated with the interference only. To this purpose LMS algorithm implementation is considered.
