1. A method of generating a notch in an Orthogonal Frequency Division Multiplexing (OFDM) frequency spectrum, comprising:

  • determining a first active interference cancellation (AIC) tone;

    comparing, using a processing component, the first AIC tone with an amplitude limit;

    in the event that the first AIC tone exceeds the amplitude limit, constraining the first AIC tone, and determining a second AIC tone based at least in part on the first AIC tone;

    wherein the first AIC tone is determined based at least in part on a plurality of peak values of a transform function.
