ABSTRACT:
In one embodiment, an MLD scheme for a wireless data communication system including steps (a)–(f). Step (a) includes calculating a first vector length for each of a plurality of complex vectors corresponding to a constellation having a plurality of combinations of possible data values. Step (b) includes selecting a subset of the combinations based on the first vector lengths calculated in step (a). Step (c) includes calculating, for a first transmitter, a second vector length for each complex vector corresponding to a combination in the subset. If there are one or more other transmitters, then, for each other transmitter, the method includes implementing steps (d) and (e). Step (d) includes reducing the subset based on the second vector lengths calculated in step (c). Step (e) includes calculating, for a current transmitter, a second vector length for each complex vector corresponding to a combination in the reduced subset. Step (f) includes generating the data based on the combination of possible data values that corresponds to the complex vector having the smallest second vector length in the subset.
