1. A method of estimating noise variance within an orthogonal frequency division multiplexing (OFDM) receiver, the method comprising: evaluating, by estimating logic associated with said receiver, a noise estimate for each of a plurality of pilots within one or more received OFDM symbols; dividing, by dividing logic associated with said receiver, the plurality of pilots into bands; calculating, by calculating logic associated with said receiver, a noise variance estimate for each band by averaging noise estimates for pilots within the band; storing the noise variance estimate for each band in memory; setting, by an interpolation engine associated with said receiver, a noise variance estimate for a pilot equal to the calculated noise variance estimate for the band which includes the pilot; and determining, by said interpolation engine, a noise variance estimate for a data sub-carrier within the one or more received OFDM symbols by interpolating between the noise variance estimates for each pilot; wherein the determined noise variance estimate is used by said OFDM receiver in decoding at least one received OFDM symbol.
