<p>A method of decoding a MIMO signal comprises steps of determining a vector of the MIMO signal and for all possible constellation points in a chosen QAM constellation undertaking a selection process to determine a likelihood. The selection process comprises determining a most likely symbol for the vector, determining a distance for the most likely symbol and determining counter hypothesis symbols. For the counter hypothesis symbols a distance from the vector for each of the bit positions in the symbols is then determined. The lowest of the distance values for each of the bit positions in the symbol when the bit is zero and when the bit is one is determined. Using the lowest distance values a likelihood value is then calculated and outputted.
