Abstract
Methods and apparatus for soft MIMO detection of high order QAM with initial candidate reduction are described. A method includes receiving a plurality of signals including Q-order quadrature amplitude modulation (QAM) symbols; determining, based on linear minimum mean square error (MMSE) estimation using detection of I and Q signs around a target layer, a reduced candidate set including C potential candidates, where C is less than Q; calculating Euclidean distances (EDs) based on the reduced candidate set; and generating log-likelihood ratio (LLR) information based on the calculated EDs.
