Patent ID: 8737546

Claim:
An Orthogonal Frequency Division Multiplexing (OFDM) receiver comprising: a channel estimator receiving a signal that includes a plurality of symbols, each of the symbols including a plurality of data subcarriers, the estimator generating a first channel response estimate of a symbol of the plurality of symbols on a first set of at least one pilot subcarrier in the signal using a Least Square algorithm, the estimator generating a set of channel response estimates of the symbol using a plurality of pre-generated weight matrices on a second set of at least one pilot subcarrier in the signal, the estimator using the first channel response estimate and the set of channel response estimates to select a weight matrix from the plurality of pre-generated weight matrices, and the estimator generating channel response estimation information for at least a subset of the data subcarriers using the selected weight matrix; and a demodulator receiving the channel response estimation information for the at least a subset of the data subcarriers from the channel estimator and using the channel response estimation information for the at least a subset of the data subcarriers to demodulate the received signal.
