摘要： Circuits detect communications from multiple transmitting antennas to multiple receiving antennas. A respective first block for each non-initial transmitting antenna determines partial distances for pairings of a first candidate and a quadrature-phase amplitude. A respective second block for the initial transmitting antenna determines partial distances for combinations of phase amplitudes. A respective second block for each non-initial transmitting antenna determines partial distances for pairings of a second candidate and an in-phase amplitude. A respective first selector for each non-initial transmitting antenna selects the first candidates from the pairings for the respective second block having smaller partial distances. A respective second selector for each non-initial transmitting antenna selects the second candidates from the pairings for the respective first block having smaller partial distances. An identifier circuit selects a final candidate with a smaller partial distance from the pairings of the respective second block for the last transmitting antenna.

摘要： 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.

摘要： A system detects symbols communicated from multiple transmitting antennas to multiple receiving antennas. A first detector determines the symbols from respective partial distances of potential choices for symbols from a constellation. A second detector determines the symbols from respective partial distances of more potential choices. The first and second detectors determine their partial distances from signals received at the receiving antennas. The second detector has a lower bit error rate than the first detector. The potential choices for the second antenna are smaller than the potential choices for the first antenna in response to a signal-to-noise ratio (SNR) being higher than a threshold. An evaluator estimates the SNR of the signals received at the receiving antennas. The evaluator enables the first detector in response to the SNR being lower than the threshold, and the evaluator enables the second detector in response to the SNR being higher than the threshold.

摘要： A circuit detects symbols communicated between multiple transmitting antennas and multiple receiving antennas (MIMO). Distance blocks are coupled in a sequence according to an ordering of the transmitting antennas. The respective distance block associated with each transmitting antenna determines a distance value for each pairing of one or more candidates and a symbol in a constellation. A respective selector block is coupled between each successive pair of distance blocks in the sequence. The respective selector block selects the one or more candidates for the successive distance block as a limited number of the pairings having smaller ones of the distance values. A limit block coupled to the selector blocks provides the limited number to each selector block. An identifier block selects the pairing having a smaller one of the distance values from the last distance block in the sequence.
