| 摘 要： | 提出了一种在有固定中继的蜂窝网络中使用信号衰落差值进行移动定位的方案.该方案不需要对网络设备和移动终端作任何硬件改造,就能普遍适用于各种无线环境和路径损耗模型,同时能有效降低阴影效应的影响.另外,结合固定中继网络的特点,通过多中继联测方式能有效提高定位精度,减小信令开销.仿真结果表明,所提出方案的独立定位精度优于传统定位方案.

| Abstract: | This paper proposed a positioning scheme based on differences of signal fading in cellular system with fixed relays.The method is adaptive to different path loss models and does not require any hardware modification on network or mobile devices.Moreover,the impact of shadowing is reduced.With the cooperative measurements provided by fixed relays,better accuracy can be achieved with less signaling cost.The simulations validate the improved performance of the proposed scheme. |
