WebMonophonic Acoustic Echo Cancellation (AEC) demo. Using adaptive filter theory, find a filter w, according to input signals (reference signal x and desired signal d), that minimises (d - w * x), where d = x * w0 + r, r is Gaussian white noise and "*" denotes convolution operation. These AEC functions are copied and modified from Behrouz Farhang ... WebFeb 24, 2011 · The three basic components of an echo canceller are an adaptive filter, a doubletalk detector and a nonlinear processor. The adaptive filter creates a replica of the echo and subtracts it from the combination of the actual echo and the near-end signal. The doubletalk detector senses the doubletalk. Doubletalk occurs when both ends are talking ... contact wavy 10
