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 is 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. A third component operable to transmit an orthogonal frequency division multiplex signal based on the time domain signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultra wideband interference cancellation for orthogonal frequency division multiplex transmitters by protection-edge tones","description":"A transmitter and communication system are disclosed.
