摘要
毫米波波段,尤其是60 GHz频段已经被认为是最有前途的并且能够分配大量频谱空间的频段。文中基于SBR/Image方法对室内非视距环境中60 GHz电波传播进行了研究,仿真结果与已知文献中的测量结果一致性良好,验证了该方法的正确性。同时,对仿真60 GHz毫米波和2.4 GHz分米波两个不同频段所得到的接收功率和均方根时延扩展等参数进行了比较与分析。通过60 GHz频段与2.4 GHz频段仿真结果比较,两者的平均接收功率和平均RMS时延扩展有着显著的差异。仿真结果表明,60 GHz比较适合近距离小范围组网,并且在短距离通信上的安全性能与抗干扰性能方面存在一定的优势,该研究为以后的毫米波通信的室内网络分布与规划奠定了理论基础。
Millimeter-wave band, especially 60 GHz band has been considered as promising band and large amount of spectral bands can be allocated space. The 60 GHz radio wave propagation characteristics of NLOS indoor environment are studied using the method of SBR/Image （Shooting and bounding ray tracing/image）. Simulation results are in agreement with measured results, thus the correctness of the method is validated. Meanwhile, some propagation parameters are obtained in the simulation at 60 GHz millimeter wave band and 2.4 GHz decimeter wave band, such as the received power and RMS delay spread, the 60 GHz frequency band compared with the 2.4 GHz frequency band, their average received power and RMS delay spread have significant difference. From the analysis ,60 GHz is suitable for small range and has performances of the safety and anti-jamming in short distances, close networking and communications. The study has laid a theoretical foundation of indoor network distribution and planning for future millimeter-wave communication.
