Abstract (en)

[origin: DE19757337C1] The echo canceller includes several groups of coefficient storage units (130,132,134) each of which is assigned to any number of N consecutive symbols of a communication signal. A selection circuit (102) is connected to a transmission channel (12) and receives a communication signal. The selection circuit is able to select a group using an actual received value and N-1 previous symbols of the communication channel. A circuit (140,150) superimposes the coefficients of a group and a communication signal in turn using the symbol clock.
