In this paper the authors give the study of the principles of Adaptive Noise Cancellation (ANC) and its applications. Adaptive noise cancellation is an alternative technique of estimating signals corrupted by additive noise or interference. In signal processing methods of removing noise, levels of noise rejection are not attainable without prior knowledge about speech signal and noise. But in this method of noise cancellation with no a priori knowledge of signal or noise, noise rejection can be achieved satisfactorily. FPGA implementation of adaptive filtering algorithm is studied in this paper.
