An Acoustic Echo Cancellation System based on Adaptive Algorithms

TL;DRAbstract

Adaptive filtering technique is one of the core technologies in digital signal processing and finds numerous application areas in science as well as in industry. Adaptive filtering technique is widely used in many applications, including echo cancellation, adaptive noise cancellation, adaptive beam forming and adaptive equalization. Acoustic echo is a common occurrence in today’s telecommunication systems. The distraction caused by the acoustic echo, reduces the speech quality in the communication. In the communication system acoustic echo cancellers is used works as the far-end signal is delivered to the system, it will be reproduced by the loudspeaker in the room. A microphone in the room picks up the resulting direct path sound and consequent reverberant sound as a near-end signal, The far-end signal is filtered and delayed to resemble the near-end signal, filtered far-end signal is subtracted from the near-end signal. The resultant signal represents sounds present in the room exclu
