摘要/Abstract

摘要： 为了探索高频段宽带无线通信的可行性，对9~12GHz高频段室内办公室场景的大尺度衰落特性进行研究。基于大量的实测数据，针对室内非视距场景下遮挡物对路径损耗的影响，提出了一种新型的具有遮挡损耗的路径损耗模型，该模型利用遮挡损耗来修正遮挡物带来的影响，且分析了遮挡物损耗与传输频率的关系，给出了不同传输频率下遮挡损耗的统计特性。研究结果表明，遮挡物静止时，遮挡损耗与接收端到遮挡物的距离满足指数函数关系，指数函数收敛速度随着频率的增大而减小；遮挡物移动时，遮挡损耗与接收端到遮挡物的距离满足二次函数关系，且随着频率的增加，最小遮挡损耗位置趋于发送端和接收端的中点。上述研究结果可为未来高频段室内无线通信系统的设计和微蜂窝网络部署提供参考与实践依据。

Abstract: To explore the feasibility of wireless communication in the high-frequency broadband, the large-scale fading characteristics of 9~12GHz in indoor office scenarios are studied. Based on a large amount of measured data, a novel path loss model with shelter loss is proposed for indoor non-line-of-sight scenarios with obstructions. The proposed model uses the shelter loss to compensate the effect caused by the shelter, and the relationship between the shelter loss and the frequency is analyzed. Moreover, the statistical characteristics of the shielding loss under different frequencies are also presented. The experimental results show that the shielding loss and the distance have an exponential function relationship when the shelter is stationary. The convergence speed of the exponential function decreases with the increase of frequency. When the shelter moves, the shielding loss and the distance satisfy a quadratic function relationship, and the position of the least shielding loss locates at the midpoint between the transmitter and the receive antennas as the frequency increases. The proposed model is benefit to the design of the future high-frequency indoor wireless communication system and the network deployment of microcells.
