Interference signal compensation

摘要

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.

1. An apparatus, comprising:
circuitry configured to receive a digital signal; circuitry configured to generate one or more cancellation coefficients based on the digital signal, wherein the one or more cancellation coefficients model one or more impulse responses of an interference signal produced by the digital signal; circuitry configured to multiply the one or more cancellation coefficients with the digital signal to generate a digital replica of the interference signal; and circuitry configured to delay the digital signal by an adjustable amount of time, wherein
the circuitry configured to receive the digital signal comprises circuitry configured to receive the delayed digital signal,the circuitry configured to generate the one or more cancellation coefficients based on the digital signal comprises circuitry configured to generate the one or more cancellation coefficients based on the delayed digital signal, andthe circuitry configured to multiply the one or more cancellation coefficients with the digital signal comprises circuitry configured to multiply the one or more cancellation coefficients with the delayed digital signal.
