摘要

超宽带技术在国内外的应用主要用于定位系统。与传统无线通信技术相比，超宽带还具有容量大、速度快、功耗低等突出优点[1]。超宽带信号在数据传输性能上也有很大的优势。提出了一种UWB MIMO系统中AOA估计相结合的方法。首先对标签位置进行定位，然后将位置信息与其他检测数据一起打包发送到基站，有利于数据传输过程。位置实时精确定位。采用MIMO技术可以提高系统的频谱效率，提高系统性能。AOA估计可以利用多天线实现精确的定位精度。

Simulation Optimization of AOA Estimation Algorithm Based on MIMO UWB Communication System

The application of UWB technology is mainly used for positioning systems both at home and abroad. Compared with conventional wireless communication technologies, UWB also has outstanding advantages such as large capacity, high speed, and low power [1]. UWB signals also have great advantages in data transmission performance. This paper proposes a method of combining AOA estimation in UWB MIMO system. Firstly, the tag position is located, and then the position information is packaged and sent to the base station along with other detection data, which is beneficial to the data transmission process. Position for real-time precise positioning. The adoption of MIMO technology can improve the spectrum efficiency and improve the system performance for the system. The AOA estimation can achieve accurate positioning accuracy by using multiple antennas.
