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.

Abstract: A method and an apparatus. The method includes receiving a signal including a serving signal and an interference signal; applying a Gaussian approximation (GA) on the serving signal and the interference signal; determining, jointly, a maximum likelihood (ML) solution of rank, traffic to pilot ratio (TPR), and precoding matrix index on the GA-applied serving signal and the GA-applied interference signal. The apparatus includes an antenna for receiving a signal including a serving signal and an interference signal; a processor configured to apply a GA on the serving signal and the interference signal, and determine, jointly, an ML solution of rank, TPR, and precoding matrix index on the GA-applied serving signal and the GA-applied interference signal.
