摘要：
The disclosed embodiments relate to reducing adjacent channel interference in an OFDM receiver. An error metric is monitored and the carrier frequency of the desired channel is slowly adjusted in response to the error metric. In this manner, the received OFDM signal, including the desired signal corrupted by the adjacent interfering channel, may be shifted until the zero crossings of the adjacent channel lineup OF the FFT bins. A multi-tap equalizer may then be used to remove the bin interference that results from the frequency offset in the desired channel.
