Abstract:
1. A method for decoding a signal vector in a multiple-input multiple-output transmission scheme, comprising: receiving multiple signal vectors corresponding to a common transmit signal vector, where each of the multiple received signal vectors has an associated channel response matrix; evaluating a set of decoding metrics for each of the multiple received signal vectors, wherein evaluating each set of decoding metrics comprises equalizing each of the multiple received signal vectors using its associated channel response matrix and, for each respective equalized signal vector, calculating a decoding metric based on a set of normalized distance calculations each computed using a different component of the respective equalized signal vector and a corresponding component of the channel response matrix associated with the respective equalized signal vector; combining decoding metrics from each of the evaluated sets of decoding metrics to produce a set of likelihood measures; selecting, for each bit of the common transmit signal vector, at least two likelihood measures from the set of likelihood measures; and estimating the common transmit signal vector, the estimating comprising decoding each bit of the common transmit signal vector based on the corresponding selected likelihood measures.
