摘要：This invention is generally concerned with methods, apparatus and processorcontrol code for decoding signals, in particular by means of sphere decoding. A spheredecoder configured to search for one or more strings of symbols less than a searchbound from an input signal by establishing a value for each symbol in turn of a candidatethe string by postulating values for each the symbol in turn of the candidate string anddetermining whether a postulated symbol value results in a distance metric dependentupon the search bound being satisfied, each the symbol of a candidate string for whichvalues are postulated defining a level of the search. The sphere decoder includes a datastructure configured to define, for each level of the search, a set of symbol values fromwhich the postulated values are selected, the sets of symbol values being different atdifferent levels of the search.
