1. A method, comprising: determining a plurality of sub-channel response estimates corresponding to a plurality of 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 sub-channels in the communication channel, wherein the plurality of weight coefficients are determined according to a minimum mean square error (MSE) technique with respect to an error between (i) the filtered sub-channel response estimate generated using the plurality of weight coefficients, and (ii) an actual sub-channel response corresponding to the filtered sub-channel response estimate; generating, with the communication device, the filtered sub-channel response estimate using (i) the plurality of sub-channel response estimates and (ii) the plurality of weight coefficients; and using the filtered sub-channel response estimate to perform, with the communication device, one or both of (i) beamforming, or (ii) equalization.
