摘要： A system and method for MIMO communications is provided. A method includes receiving a data block of P matrices from a transmitter, and determining if operating conditions are met. The method also includes if operating conditions are not met, computing a test position, selecting a codeword based on the test position, and computing a metric. The metric may then be compared with an error radius to determine a validity of the codeword. If the codeword is invalid, another codeword is selected. If the codeword is valid, then the codeword is stored if all matrices have been evaluated, else another matrix is selected for evaluation. If matrices earlier in the data block have untested codewords while all codewords for a matrix being evaluated have been tested, backtracking may be performed. After the codewords for the data block have been found, the stored data may be outputted and processed.
