Abstract:
1. A transmitter, comprising: a first component operable to determine an active interference cancellation value for each of a plurality of active interference cancellation tones and a protection-edge value for each of a plurality of protection-edge tones based on optimizing active interference cancellation, and further based on constraining an average power of the active interference cancellation values and the protection-edge values to less than or equal to a maximum power level, and on a plurality of data values; a second component operable to transform a sequence of tones to a time domain signal, the sequence of tones comprised of the active interference cancellation tones, the protection-edge tones, and a plurality of data tones, the data tones containing the data values; and a third component operable to transmit an orthogonal frequency division multiplex signal based on the time domain signal.
