Abstract
In this paper, the basic emphasis is on
implementation of a new scheme of noise and echo
cancellation from speech signals using adaptive filtering
techniques. The proposed model can be divided into two
major parts: acoustic echo canceller and background noise
canceller; both parts are kept independent of each other so
that time-variance in background noise canceller does not
affect the echo canceller. Echo cancellation is done by
correlating far-end echo with input signal and the core of
noise cancellation of this scheme lies in cascading technique
for reconstruction of noise.
