• 論文の詳細を見る

• This letter contains our proposal for a new iterative decoding algorithm for Turbo coded V-BLAST system. The proposed algorithm is based on maximum a posteriori (MAP) decision criterion. In a V-BLAST system concatenated with Turbo codes, the extrinsic information from the soft output channel decoder can he utilized as a priori probability, making it possible to apply MAP decision criteria to the V-BLAST decoding process. The MAP decision criterion is applied to the V-BLAST ordering and slicing procedure, resulting in a considerable gain in hit error performance. As the iteration rate increases, the proposed system exhibits performance similar to that of system with ideal sliced.
