Abstract
An efficient method for real-time periodic interference suppression on tele phone lines is proposed. The periodicity of the interference is exploited b y an adaptive phase-locked buffer (APLB), which is used to create the antip hase noise replica. Computer simulations are used to compare the APLB appro ach with the traditional least mean squares (LMS) algorithm in an adaptive noise cancellation configuration. The new technique outperforms the LMS noi se canceller and proves to be a very efficient solution to the power line i nterference problem.
