US Patent 10460762 Cancelling adjacent track interference signal with different data rate

An apparatus may comprise a circuit configured to receive first underlying data corresponding to a first signal with a first rate and receive a second signal with a second rate corresponding to second underlying data. The circuit may interpolate the first underlying data to generate a plurality of interpolated signals, determine, for the first signal, a first channel pulse response shape with the first rate, and determine an interference component signal based on the plurality of interpolated signals and the first channel pulse response shape. The circuit may then cancel interference in the second signal using the interference component signal to generate a cleaned signal.
