Abstract
A method of decoding a transmitted string of symbols received as a received signal. The method includes searching for a candidate string of symbols, by searching for candidate symbols within a region of a multi-dimensional lattice, and decoding the transmitted string of symbols by selecting a candidate string of symbols. The candidate string of symbols includes a string of candidate symbols. The searching for the candidate symbols includes selecting a candidate value for one of the transmitted symbols, and testing whether a part of the multi-dimensional lattice defined by the selected candidate value is within a bounding distance from the received signal. The searching for the candidate symbols is stopped after a limiting number of performances of the testing. The decoding includes providing a linear estimate of the transmitted string of symbols when the searching for the candidate string of symbols fails to locate the candidate string of symbols.
