Abstract
A circuit detects symbols transmitted from multiple transmitting antennas to multiple receiving antennas. A distance block for an initial transmitting antenna in an ordering of the transmitting antennas determines a distance value for each symbol in a constellation. A selector block selects a limited number of candidates for the initial transmitting antenna from the symbols having smaller distance values. For each first and successive second transmitting antenna in the ordering, a distance-selector block selects a candidate for the second transmitting antenna for each candidate for the first transmitting antenna. The candidate for the second transmitting antenna is a pairing having a smaller distance value among the pairings of the candidate for the first transmitting antenna and the symbols. An identifier block selects a last candidate having a smaller distance value among the candidates for a last transmitting antenna in the ordering. The last candidate includes the detected symbols.
