摘要
利用理论和实验相结合的方法研究了室内宽带端到端(Device-to-Device,D2D)无线信道信号的幅度和多普勒频谱分布.结果表明:在不同的场景下,D2D信号幅度分布服从单瑞利、双瑞利和多瑞利的复合分布;在二维(Two-Dimension,2-D)和三维(ThreeDimension,3-D)散射环境下随电波到达角的分布不同,D2D信道多普勒频谱将遵循不同的分布规律.通过理论和实验结果的比较研究验证了本文结果的正确性.
In this paper,based on the joint theoretical and experimental research on indoor device-to-device(D2D)radio channels,the signal amplitude and Doppler spectra distributions in D2 Dindoor radio channels are investigated.The results show that the signal amplitude follows single,double,and multiple Rayleigh distributions at different indoor scenarios.Different distributions of the angle-of-arrivals(AoAs)in the azimuth and elevation planes can result in different Doppler spectrum distributions in 2Dand 3D scattering environments.The correctness of the theoretical results is tested with the experimental results.
