Combining Alamouti coding with V-BLAST through dynamic antenna grouping
V-BLAST is combined with Alamouti coding in MIMO systems to take advantages of both spatial diversity and multiplexing techniques. Based on the optimal detection ordering information generated in the conventional V-BLAST systems, several bits feedback information was built without any additional com...

| description | V-BLAST is combined with Alamouti coding in MIMO systems to take advantages of both spatial diversity and multiplexing techniques. Based on the optimal detection ordering information generated in the conventional V-BLAST systems, several bits feedback information was built without any additional computational complexity and then the transmit antennas are dynamically divided into two groups: the two weakest antennas are grouped for Alamouti coding and the rest antennas operates as V-BLAST. Through dramatically improving the BER performance of the first detection stage and suppressing the error propagation effect, the proposed algorithm achieves better BER performance over V-BLAST with same spectral efficiency, and it can be applied in the MIMO systems in which the number of transmit antennas is more than that of the receive antennas. |
