Echo compensation for transmission systems |
摘要 |
For the purpose of identifying automatically the transmission properties of the system, the error signal is employed to adjust the least mean square algorithm to a delay time measured in scan units. Each estimate value for the echo is subtracted from the echo of the system. Also, a correction signal is added to the error signal and an expression is given for the calculation.
