Abstract: In an embodiment, a multi-carrier signal (e.g., an OFDM signal) is received over a channel. First indicators of interference and channel response at a carrier frequency of the signal are determined and compared. If the first indicator of the interference has a relationship to the first indicator of the channel response, then a data value transmitted at the carrier frequency is recovered from a data value received at the carrier frequency according to a first algorithm. If, however, the first indicator of the interference does not have a first relationship to the first indicator of the channel response, then second indicators of interference and the channel response at the carrier frequency are determined and compared. If the second indicator of the interference has a second relationship to the second indicator of the channel response, then the data value transmitted at the carrier frequency is recovered from the data value received at the carrier frequency according to a second algorithm.
