Add to ORKGThe aim of this work is to investigate methods for restoring signals that are corrupted by one or more echos. Echo commonly occur over communication channels such as telephone and ADSL lines. A reasonable model of the echo process at the time domain has been proposed. The echo removal system is modeled as an FIR filter with an unknown impulse response. We estimate the required impulse response by transmitting a known signal x [n] over the channel and observing the corresponding output y[n]. We want a system that takes the echo signal y[n] as input, and outputs the original signal x[n]. Keywords: Echo cancelation, FIR filter, Least Mean Square (LMS
