Claim:
A method comprising: determining a plurality of sub-channel response estimates corresponding to a plurality of contiguous sub-channels in a communication channel; determining, with a communication device, a plurality of weight coefficients to be used in generating a filtered sub-channel response estimate for a first sub-channel of the plurality of contiguous sub-channels, wherein the plurality of weight coefficients are determined such that, when the filtered sub-channel response estimate is generated using the plurality of weight coefficients, a mean square error (MSE) between a filtered sub-channel response estimate and an actual sub-channel response corresponding to the filtered sub-channel response estimate is minimized; multiplying, with the communication device, the plurality of sub-channel response estimates with the plurality of weight coefficients to generate a plurality of weighted sub-channel response estimates; and generating, with the communication device, the filtered sub-channel response estimate for the first sub-channel using the plurality of weighted sub-channel response estimates.
