摘要： In a MIMO receiver, initial solutions using sub-optional decoding algorithm are determined for the symbols transmitted from each of a number of transmit antennas at a given time (100). The initial solutions (Sinit1,..., SinitNt) are hard-mapped to the nearest possible symbols of transmission (Sest1,..., SestNt). For each of the nearest possible symbols limited areas around them in the constellation plane are defined. A list of candidate symbol vectors (list) is then determined, including only symbols lying within the limited areas of the constellation plane. Finally, a joint decoding technique such as ML-technique is implemented to determine the best of the candidate symbol vectors. The number of the calculations can thus be significantly reduced, without having excessively damaging effects on the symbol error rate.
