A method includes receiving a signal at a receiver device via a channel from a transmitter device and determining a frequency domain representation of the signal. The signal includes multiple modulation symbols. The method further includes detecting a first symbol of the signal and determining a time domain representation of a distortion estimate associated with the first symbol using a distortion recovery receiver (DRR) technique. The method further includes subtracting the distortion estimate from the first symbol to generate an updated estimate of the first symbol. The method further includes determining a frequency domain representation of a second symbol using a value that is based on a frequency domain representation of the distortion estimate and that is further based on a frequency domain representation of a quantized version of the updated estimate of the first symbol.

A wireless communication system includes first and second transceivers operable to transmit and receive signals over a communication channel using a plurality of modulation modes. A first signal is received which has been transmitted using a first modulation mode over the communication channel from the first transceiver to the second transceiver, and a first channel equalization characteristic for an equalizer of a first type for receiving the first signal at the second transceiver is determined from measurements of the communication channel. From the first channel equalization characteristic, a second channel equalization characteristic is determined for an equalizer of a second type for a second modulation mode. A measure of a difference between the second and the first channel equalization characteristics is determined, and the second modulation mode is selected for transmission over the communication channel from the first transceiver at least in part in dependence on the measure.
