Abstract:
A method of operating a communication system including at least one receiver comprising:providing to the receiver a plurality of time-domain Doppler channel estimates for at least one transmitter, a plurality of Doppler sinusoids, and a spatial covariance matrix of a corrupting environment; determining a Doppler spatial covariance matrix as a function of the time-domain Doppler channel estimates and the Doppler sinusoids; determining a total Doppler spatial covariance matrix as a function of the spatial covariance matrix of the corrupting environment and the Doppler spatial covariance matrix; determining a Doppler steering vector for at least one transmitter as a function of the Doppler channel estimates and the Doppler sinusoids; and determining a combining weight for the at least one transmitter as a function of the total Doppler spatial covariance matrix and the Doppler steering vector for at least one transmitter.
