Abstract
Techniques are provided to support successive interference cancellation (SIC) receiver processing with selection diversity whereby each of Ntransmit antennas may be turned on or off. One symbol stream may be transmitted from each transmit antenna. A SIC receiver recovers the transmitted symbol streams in a specific order. Up to N! orderings are evaluated. For each ordering, Npost-detection SNRs are obtained for Ntransmit antennas and used to determine Ndata rates, where the data rate is zero if the post-detection SNR is worse than a minimum required SNR. An overall data rate is computed for each ordering based on the Ndata rates. The ordering with the highest overall data rate is selected for use. Up to Nsymbol streams are processed at the data rates for the selected ordering and transmitted. The transmitted symbol streams are recovered in accordance with the selected ordering.
