Patent ID: 6937665

Claim:
A method of transmitting data signals from at least two transmitting terminals, with each having at least one transmitting means, to at least one receiving terminal having a spatial diversity receiving means, the method comprising: transmitting from the transmitting terminals transformed data signals, being transformed versions of respective data signals, wherein spectra of the transformed data signals are at least partly overlapping; receiving on the spatial diversity means received data signals, wherein the received data signals are each a function of one of the transformed data signals; subband processing of the received data signals in the receiving terminal; and determining estimates of the respective data signals, on a subband by subband basis, from the subband processed received data signals in the receiving terminal, wherein said determining includes, for at least one data signal: selecting from the data signals a selected data signal; determining an estimate of the selected data signal from the subband processed received data signals; modifying the subband processed received data signals based on the estimate of the selected data signal; and determining estimates of the remaining data signals from the modified subband processed received data signals.
