论文摘要
在本文中，有改进的可见光通信通道模型（VLC）用于介绍。对于VLC的室内通道模型，根据接收的信号强度估算距离。在此模型中，收到的射击噪声是距离估计准确性中的距离依赖性参数。此外，基于此模型，Cramer-Rao下限被计算为任何无偏估计器的性能和准确性的理论限制。通过这种方式，研究了水平和垂直距离的影响。此外，还展示了对RSN以及CRLB上的传输功率效应。
In this paper, an improved channel model of visible light communication (VLC) for ranging in presented. For indoor channel model of VLC, distance is estimated based on received signal strength. In this model, received shot noise as a distance-dependent parameter is considered in range estimation accuracy. Moreover, based on this model, the Cramer-Rao lower bound is computed as the theoretical limits on the performance and accuracy of any unbiased estimator. In this way, the effects of horizontal and vertical distances are investigated. In addition, the transmitted power effect on RSN and accordingly on CRLB is demonstrated.
