| 摘 要： | 针对时分长期演进多输入多输出系统中的多码字传输模式，分析自适应调制编码和混合自动请求重传对排序串行干扰消除检测顺序的影响，提出一种新型的排序串行干扰消除迭代检测译码算法，并分析该算法的复杂度. 仿真结果表明该算法能够有效提高系统吞吐量，且码字调制编码等级差异越大，MIMO阶数越高，该算法的性能增益越明显.

| Abstract: | This paper proposes an iterative detection decoding algorithm based on ordered successive interference cancelation(OSIC) for time division long term evolution(TD-LTE) multi-input multi-output(MIMO) systems.In the algorithm a multiple-codewords transmission mode is used,and the effects of adaptive modulation and coding(AMC) and hybrid automatic repeat request(HARQ) on the detection order are taken into consideration.Computation complexity of the algorithm is analyzed.Numerical results show that the proposed method can significantly improve throughput.The performance gain increases with the increase of gaps between modulation and coding levels of multiple codewords,and the increase of the number of transceiver antennas. |
