Claim:
1. A method for decoding multiple input multiple output (MIMO) signals by calculating log-likelihood ratios in a communication receiver, the method comprising: receiving, by the communication receiver, samples of one or more spatial streams; determining one or more demodulated samples of the received samples by applying one or more discrete Fourier transforms; determining one or more subsymbols from the demodulated samples by utilizing a multiple input multiple output (MIMO) detection method; calculating a log-likelihood ratio for each bit of one or more subsymbols of each of the one or more spatial streams by using Γ computing an effective noise on the one or more spatial streams after considering noise terms resulting from the multiple input multiple output (MIMO) detection estimates of the one or more subsymbols on the one or more spatial streams,
