Methods and apparatus for low complexity soft-input soft-output group detection
Certain aspects of the present disclosure propose methods and apparatus for low complexity soft-in soft-out detection that divide a plurality of received symbols into a plurality of groups of symbols and performs preprocessing on the symbols in each group to suppress interference from other groups. The preprocessing may utilize a priori information for one or more symbols in one or more groups that are not yet detected, and/or a posteriori information for one or more symbols in one or more groups that are already detected and/or decoded. The preprocessed symbols may then be detected using a soft-in soft-out detection algorithm.
