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 line up with the
FFT bins. A multi-tap equalizer may then be used to remove the inter-bin
interference that results from the frequency offset in the desired
channel.
