US 12,063,056 B2 · Interference cancellation in a transceiver device

Abstract

The present disclosure is directed to improvements in interference mitigation for Adjacent Channel Leakage in wireline communication, and more specifically, but not exclusively, to improved kernel designs that can facilitate interference mitigation for Adjacent Channel Leakage in cable modem systems. Examples of the present disclosure provide an apparatus for a transceiver device that comprises interference cancellation circuitry configured to cancel interference caused by upstream signals in one or more upstream sub-bands on one or more downstream sub-bands based on a combination of a plurality of kernels. The interference is at least partially caused by non-linearities within a transmission circuitry of the transceiver device, the plurality of kernels representing the non-linearities within the transmission circuitry of the transceiver device. Each of the kernels comprises one or more associated terms, with each of the associated terms being in-band for at least one of the one or more downstream sub-bands.
