Abstract
An apparatus includes a demapper to compute a reliability metric associated with a number of bit streams received by multiple radio-frequency (RF) antennas. The apparatus further includes a channel decoder in a feedback loop with the demapper to process the reliability metric and to provide a feedback signal to the demapper. The demapper is an iterative demapper and can use a symbol subset of at least a first stream of the plurality of bit streams and the feedback signal to compute the reliability metric for a second stream of the plurality of bit streams.
