DESIGN OF FPGA BASED ADAPTIVE FILTER BASED ON LMS ALGORITHM FOR ECHO CANCELLATION

Traditional telephony uses only a single receiver f or speech acquisition. If the speaker is standing a way from the telephone,the signal will be weak and there will be interference sources from room reverberation. In addition,there is acoustic echo coming from the loudspeaker,which further interferes with the signal of interest. This research investigated the combination of common solutions to these problems. Echo Cancellation is a n occurrence in today�s communication systems. The interferences caused by acoustic echo are distracting to the users and redu ce the quality of the voice. Echo cancellation remo ved the echo coming from the loudspeaker. https://www.ijiert.org/paper-details?paper_id=14056
