基于MIMO技术的无线定位精度改进

IMPROVING WIRELESS POSITIONING PRECISION BASED ON MIMO

无线定位是无线传感网络(WSN)中的关键技术之一。结合环境因素,提出一种基于MIMO(Multiple-Input Multiple-Output)的误差补偿方法。充分利用参考节点采集的数据,列出不同的误差补偿值,根据不同的采集值对移动节点进行定位,提高了局域网内的高精度定位。

In wireless sensor networks （WSN）, wireless positioning is one of the key techniques. In this paper, combining with the environmental factors, we propose an MIMO （multiple-input and multiple-output）-based error compensation method. It makes full use of the data collected from reference node and lists different error compensation values, it positions the mobile node according to different acquisition values, and improves the high precision positioning within the local area network.
