1. An apparatus, comprising:

  • an equalizer that is operable to;

    receive a signal from a communication channel, wherein the signal includes additive white noise and a frequency response of the communication channel includes a null at a frequency; and

    equalize the signal using an inverse, zero forcing response that includes a peak at approximately the frequency of the null within the frequency response of the communication channel thereby transforming white noise within the signal to become colored noise located at approximately the frequency; and

    a canceller that is operable to perform interference cancellation on the colored noise located at approximately the frequency.
