Abstract:
An electronic MIMO-OFDM carrier frequency recovery method is disclosed. The method includes receiving a wirelessly propagated time-domain signal observation, estimating a data-channel vector from a latest observation vector by correcting for a phase rotation effect based on an initial estimate or an up-to-date estimate of a phase rotation term, removing an effect associated with the data-channel vector from the latest observation vector using the estimated data-channel vector to obtain an up-to-date estimate of the phase rotation term; and repeating those prior acts iteratively to allow for production of FFT input samples that are free or nearly free of carrier frequency and phase error.
