Claim:
1. A method, comprising: receiving pilot signals on multiple subchannels of a resource block associated with one or more user devices; computing channel estimation matrices for the subchannels of the resource block; determining a linear regressor that relates the computed channel estimation matrices for the subchannels to a subchannel number; selecting an anchor subchannel for the resource block; computing weights for each subchannel of the resource block using the linear regressor and a distance that the subchannel is away from the selected anchor subchannel; computing channel estimation matrices for each subchannel in the resource block by weighting the channel matrices for the subchannels based on the weights that are determined for the corresponding subchannel; computing precoding matrices for each subchannel in the resource block from the channel estimation matrices determined for the corresponding subchannel; applying one or more of the computed precoding matrices to one or more signals for generating one or more modified signals; and communicating, via a corresponding subchannel of the resource block, the one or more modified signals to the one or more user devices.
