摘要 相对于传统的单天线系统,M IMO(多输入多输出)技术能够大大提高频谱的利用率,因而被认为是新一代移动通信系统的关键技术。格点减少算法从一个全新的角度解决了多输出信号的检测问题,具有良好的发展前景。文中简要介绍了格点减少算法的数学原理,详细介绍了格点减少算法在M IMO信号检测中的应用,并在分析其性能和计算复杂度的基础上,比较了格点减少算法与其他检测算法的差异。 Compared to the traditional single-antenna system, MIMO technology can greatly improve spectrum utilization, so it is the key for new generation of mobile communication systems. A new Lattice-Reduction Algorithm for the detection scheme is proposed here from an entirely new point of view, and its future development is predicted. In this paper, we briefly introduce the principle of Lattice-Reduction, and investigated the application of Lattice-Reduction Algorithm for the detection scheme of MIMO systems in detail. Through a complete analysis of the performance and the computational complexity, we compared the difference between Lattice-Reduction Algorithm and other signal detection schemes.
