Abstract:
1. A method for codeword selection in a multi-input multi-output (MIMO) communication system, the system having multiple transmit antennas and multiple receive antennas, the method comprising: providing codeword candidates by a transmitter; receiving the multiple codeword candidates by a receiver to determine bit error rates, each corresponding to one of the codeword candidates according to a decoding strategy; finding a codeword candidate with the minimum bit error rate and sending a selection signal to the transmitter; and determining a codeword for data transmission according to the selection signal, wherein each of the codeword candidates employs Nq antennas, with Nq being equal to 2, 3 or 4 and the antenna numbers of the codeword candidates are different from each other.
