Abstract:
1. A communication method comprising: receiving data signals from at least two transmitting terminals at a receiving terminal comprising a spatial diverse receiving device, wherein the received data signals are each a function of respective transformed data signals, the transformed data signals being transformed versions of a data signal received by the at least two transmitting terminals; subband processing of the received data signals at the receiving terminal; and determining estimates of a value of the data signals, on a subband by subband basis, from the subband processed received data signals, wherein said determining includes, for at least one received data signal: selecting from the received data signals a selected data signal; determining an intermediate estimate of the selected data signal from the subband processed received data signals; modifying the subband processed received data signals based on the intermediate estimate of the selected data signal; and determining intermediate estimates of the remaining data signals from the modified subband processed received data signals; wherein determining the intermediate estimates of the data signals is based at least upon distinct spatial signatures of the received data signals.
