| 摘 要： | 针对多输入多输出系统,提出了一种新的空时分层低密度校验编码方案。通过引入相邻层间的关联矩阵,在对当前层译码时,对下一层的数据信息起到一定保护作用,从而减轻错误的传播。实验结果表明,在相同的信噪比下,能获得比V-BLAST方案低的码字差错率。

| Abstract: | In this paper,a new space-time layered LDPC for MIMO system is proposed.The correlation matrix between two serial layers is introduced.When decoding current layer,it can provide better protection on the information of next layer.Thus,the error propagation is eased or even removed.Simulation results show that the proposed scheme performs better than V-BLAST in the same SNR. |
