Abstract
A method for processing a plurality of data streams from a transmitter, includes: receiving symbols via the plurality of data streams; generating a channel matrix; sorting the channel matrix to provide a sorted channel matrix; performing QR decomposition on the sorted channel matrix and a column-row-swapped-sorted-channel matrix; performing QR equalization on a sorted received symbol vector and a swapped received symbol vector to provide a equalized-sorted vector and a equalized-swapped-sorted vector; processing first and second portions of the equalized-sorted vector and the equalized-swapped-sorted vector via a QR-MLD demodulation scheme to determine soft bits and soft symbols; and rearrange soft bits in the above steps to provide an output vector.
