The Group Iiterative QR Detection Algorithm

该文首先介绍了结合空时分组码的垂直分层空时码多输入输出正交频分复用系统,即分层空时分组码系统及其典型系统模型和典型的分层空时分组码系统检测算法,研究了基于A lamouti空时编码的分层空时分组码系统的QR检测算法,分析给出了简化的QR运算过程,根据迭代和干扰消除思想,提出了一种改进的检测算法,即分组迭代QR检测算法。理论分析和仿真结果都表明分组迭代QR检测算法以较低的计算复杂度获得了较好的性能。

In order to increase the coding gain, we study the space-time block coding （STBC） technology combined the V-BLAST, MIMO-OFDM system, that is LSTBC system. Then the system model is given and the classical QR detection algorithm is analyzed. On this basis, this paper presents a group iterative QR detectioa algorithm with lower complexity. The simulation results show that the proposed algorithm can obtained better performance than the classical QR detection algorithm.
