Abstract:
1. A system for detecting symbols communicated between multiple transmitting antennas and multiple receiving antennas, comprising: means for selecting a respective limit number for each transmitting antenna in response to a total power received at the receiving antennas from the transmitting antenna; for each transmitting antenna in an ordering of the transmitting antennas, means for determining a distance for each pairing of at least one candidate for the transmitting antenna and one of a plurality of symbols in a constellation, wherein the at least one candidate for a first transmitting antenna in the ordering is a null candidate; means for selecting the at least one candidate for a next transmitting antenna following each transmitting antenna in the ordering as a subset of the pairings that have smaller values of the distances for the transmitting antenna, wherein a size of the subset is limited to the respective limit number for the transmitting antenna; and means for selecting a final candidate as the pairing that has a smaller value of the distances for a last transmitting antenna in the ordering, wherein the final candidate includes the symbols detected as transmitted by the transmitting antennas.
