Abstract:

A new ordering method and detection algorithm based on the Schmidt decomposition for the multiple－input multiple－output (MIMO) system are proposed. The algorithm can achieve the same bit error rate （BER） performance as the traditional zero forcing serial interference cancellation (ZF－SIC ) algorithm while the computational complexity of the proposed algorithm is 1/3 to 2/3 to the traditional ZF－SIC algorithm. Analysis and computer simulation are also presented to verify the algorithm.
