    Abstract: ECHO cancel ic
    Text: echo cancellation (AEC), line echo cancellation (LEC), and adaptive noise suppression (ANS). The , line echo cancellation function cancels the near-end speech that has been reflected at the network switch and transmitted back to the cellular phone. The principle of the line echo cancellation function is very similar to that of the acoustic echo cancellation function. The difference is that the line , impedance mismatch in the network circuit. The line echo cancellation function is capable of canceling a
