Abstract
A method of estimating and/or tracking time varying radio channels comprises the step of receiving signals transmitted over the channels and converting the signals to digital samples for processing. Positions of fading rays of the channel medium are determined. Impulse response of a channel medium are estimated for each of the estimated positions. Estimates of the time varying radio channels are then calculated using the digital samples and the estimated impulse responses.
