<p>A node comprising a receiver for i) receiving at least two signals streams comprising bit sequences and ii) evaluating which bit sequence that is most likely to have been received for a certain sent symbol for each signal stream. The receiver for calculating metrics indicative of which bit sequence that initially is most likely to correspond to a certain sent symbol, the metrics being used a soft value calculation where the receiver is arranged for addition of metric data for a certain signal stream corresponding to an added bit sequence for each case where the available metrics are incomplete for performing the estimation. The missing bit is inserted in the added bit sequence and chosen such that it corresponds to a symbol with the shortest Euclidian distance to the symbol with the said corresponding bit sequence initially being indicated as most likely to correspond to a certain sent symbol.</p> |
