However, the standard decoding method is not the most efcient. A few of researchers made some changes based on the standard decoding method and achieved considerable performance. In this paper, a synthetic decoding method is presented according to the existing enhanced decoding method and the simulation shows that the syn- thetic way outperforms any other ways.展开更多
