WebAbstract: In this paper we present a method for echo detection and echo path delay estimation using a pattern recognition approach. We consider the problem of echo … WebThe typical echo path response is formed by a "pure delay" element and a "tail delay" The pure delay is the actual propagation time taken by the signal from its source (e. g., the echo canceller) to a hybrid and backwards. The "tail delay", on the other hand, is the response of the hybrid circuit which terminates the four-wire line and performs ...
