摘要： In a receiver first stage, received signals are equalized using first stage channel estimates, a first data stream is separated from a second data stream; and interference on the first data stream is re-generated by filtering the decoded first data stream (after decoding) using the first stage channel estimates. Second stage channel estimates are calculated using the first stage channel estimates and gain derived from generating the interference, and the interference is subtracted from the received signals. In the receiver second stage, the signals from which the interference was subtracted are equalized using the second stage channel estimates, the second stream of data is decoded; and the decoded first data stream and the decoded second data stream are output. One embodiment gets channel estimates for each stage from the received signal and regenerates pilot interference; the other calculates updated channel estimates from the first stage for use in the second stage.
