<p>A method of frequency offset estimation and correction for adaptive antennas comprises receiving in a processor samples of a data set having a training data sample sequence. A batch least squares weight solution is computed for the training data sample sequence to obtain a least square error for each sample. Each error sample is rotated by multiplying by the conjugate of a sample of the reference training sequence and each rotated error sample is numbered (in the order received). A straight line is fit to the imaginary part of the rotated error sample (as a function of sample number) to obtain a frequency offset estimate. Each sample in a time slot of the samples of a dataset is multiplied by a complex exponential function of the frequency offset estimate.</p> |
