Abstract
Aspects of this disclosure relate to canceling a tone in a radio signal. A location of an interfering tone can be estimated in an orthogonal frequency division multiplexing symbol (OFDM). An interfering tone can be detected in a subsequent OFDM symbol based on the estimate of the location of the interfering tone in the OFDM using closed loop tone detection. The interfering tone in the subsequent OFDM can be canceled. Tone cancellation can be performed using digital signal processing circuitry. Tone cancellation can be performed in radio systems.
