DEVICE AND METHOD FOR DETECTING TRANSMITTED SIGNALS IN A MIMO COMMUNICATION SYSTEM

摘要

A signal detection method performed by a MIMO receiver, comprises performing maximum likelihood detection, MLD, including QR decomposition, M-algorithm and multiple quadrant detection, MQD, wherein estimating expected Euclidean distances comprises looking up precalculated values of Euclidean distances between symbol replicas and a plurality of regions in the symbol constellation area from a look-up table.
