Abstract
A method of calculating at least one soft bit corresponding to a data symbol received by a radio receiver is described. In one form the method () includes, calculating an average amplitude at least one received data symbol. The method also includes calculating () at least one threshold amplitude in respect of the data symbol on the basis of the calculated average amplitude. Next a subset of constellation symbols is determined () at least partly on the basis of the at least one threshold, and for which a distance determination will be made. The distance between the position of the data symbol and each of the symbols in the subset of constellation symbols is determined () and then a soft bit corresponding to the received symbol is calculated () on the basis of said determined distances.
