Abstract
The proposed solution includes storing for a given number of modulation methods, for each modulation symbol, information on neighboring symbols in the symbol constellation of the modulation method, receiving as an input a Multiple Input Multiple Output signal including modulation symbols in two or more layers; providing hard decisions of the modulation symbols for each layer; determining neighbors for each hard decision; for each hard decision of a layer, going through at least some of the neighbors and evaluating a cost function, selecting a symbol based on the evaluation and repeating this for each layer.
