Abstract
In some implementations, an apparatus includes an echo canceller that generates an echo interference compensation signal that compensates for an echo interference signal in a communication signal, a crosstalk canceller that generates a crosstalk interference compensation signal that compensates for a crosstalk interference signal in the communication signal, and a combiner that generates a combined interference compensation signal based on the echo interference compensation signal and the crosstalk interference compensation signal.
Claims20
An apparatus comprising:
- an echo canceller that generates an echo interference compensation signal that compensates for an echo interference signal in a communication signal, wherein the echo canceller generates echo cancellation coefficients in a time domain based on a time domain signal that produced the echo interference signal in the communication signal, and generates the echo interference compensation signal based on the echo cancellation coefficients and the time domain signal;
- a crosstalk canceller that generates a crosstalk interference compensation signal that compensates for a crosstalk interference signal in the communication signal;
- and
- a combiner that generates a combined interference compensation signal based on the echo interference compensation signal and the crosstalk interference compensation signal.
