Abstract: A receiver includes a radio frequency (RF) front end receives a received signal that is modulated via orthogonal frequency division multiplexing (OFDM) and generates a downconverted signal, based on the received signal. An OFDM demodulator generates subcarrier data based on the downconverted signal. The subcarrier data corresponds to a plurality of subcarriers. A subcarrier weighting module generates weighted subcarrier data by applying subcarrier weights to the subcarrier data corresponding to selected ones of the plurality of subcarriers. An OFDM decoder generates decoded OFDM data based on the weighted subcarrier data.
