| 摘 要： | 局部无线定位技术是基于局部组网的低成本和低复杂度的定位技术。在局部无线定位中,无论采用哪种技术,都会受到非视距和多径传输的影响,给定位带来较大的误差。环境建模可以通过曲线拟合的方式来建立某些典型场景的信号传输模型。除此之外,在前期环境建模完善的条件下,进一步提高精度只能依靠监控端软件中几何定位算法的改进。文章提出了一种...

| Abstract: | Localized wireless positioning technique is based on the low-cost and low complexity local network.It can be achieved by applying on of the following techniques: Received Signal Strength Indication(RSSI),Link Quality Indication(LQI) or Time Of Arrival(TOA).However,no matter which technique is applied,the system performance will be affected by non line of sight and multiple-path transmission,which brings deviation in positioning.The establishment of environment model can be achieved by fitting values to a cu... |
