摘要

信号检测是三维多输入多输出(3D-MIMO)无线通信系统的基本问题之一。本文研究了三维多输入多输出系统中的信号检测问题，其中考虑了矩阵近似反演技术。众所周知，在MIMO系统中，非线性信号检测算法的信号检测精度比线性信号检测算法有所提高，但在实际应用中对硬件的要求更高。因此，在MIMO系统中需要一种更容易实现的线性信号检测算法。研究了基于线性方程生成的等效矩阵反演方法，介绍了基于矩阵近似反演的大规模三维MIMO系统信号检测方案。

Matrix Approximate Inversion Based Signal Detection in Large-scale 3D-MIMO Systems

Signal detection is one of the fundamental problems in three-dimensional multiple-input multiple-output (3D-MIMO) wireless communication systems. This paper addresses a signal detection problem in 3D-MIMO system, in which matrix approximate inversion techniques is considered. It is well known that the signal detection accuracy of nonlinear signal detection algorithm is improved compared with the linear signal detection algorithm in MIMO systems, but its hardware requirements are higher in practical applications. Therefore, a more easily implemented linear signal detection algorithm is needed in MIMO systems. This paper studies the equivalent matrix inversion method based on linear equation generation and introduces the signal detection scheme based on matrix approximate inversion in large-scale 3D MIMO systems.
