Abstract
Embodiments relate to systems, methods, and computer readable media to enable a wireless receiver are described. In one embodiment a wireless receiver includes a channel decoder and a Soft-Input Soft-Output Multiple-Input Multiple-Output detector (SISO MIMO detector). The SISO MIMO detector includes circuitry to generate soft symbol outputs for each of a plurality of received spatial streams, and circuitry to adjust a signal to noise plus interference ratio for the soft symbol outputs using channel statistics and using hard decisions from an output of the channel decoder. The channel decoder is configured to receive soft binary information generated from the soft symbol outputs from the SISO MIMO detector and perform these steps iteratively a number of times.
