Abstract
An apparatus includes a demapper to receive a number of bit streams received by multiple radio-frequency (RF) antennas. The demapper can compute a first reliability metric associated with a first stream and a second reliability metric associated with a second stream. A channel decoder processes the first and the second reliability metrics to recover decoded data. The demapper is a reduced complexity demapper and uses a symbol subset of the first stream to compute, by employing look-up tables, the second reliability metric for the second stream.
