39GHz室外微蜂窝信道测量、建模与仿真研究
Millimetre-wave channel measurements, modeling and simulation for outdoor microcells at 39 GHz
摘要
Abstract
In this paper,based on an outdoor microcell channel measurement campaign at 39 GHz,the path loss model,shadow fading and other large-scale parameters(LSP) in mm-wave band are studied.The signal model by using space-alternating generalized expectation-maximization(SAGE) for directional-scansounding measurement and modeling is introduced.Moreover,an optimized clustering algorithm and Ricean K-factor extraction method are also proposed.Multipath parameters are extracted by SAGE,and then we use the optimized clustering algorithm to get cluster level parameters,including cluster delay spread,angle spread and number of clusters.The quasi-deterministic radio channel generator (QuaDRiGa) platform recommended as the 5th generation(5G)mobile communication simulator by the 3rd generation partnership project (3GPP) is verified at 39 GHz by measurements.The results show that the directional and omni-directional path loss models in line-of-sight (LOS) scenarios is close to free space when using both the fixed and floating intercept path loss models.The statistical results for LSPs in this work agree well with the results in millimetre-wave based mobile radio access network for fifth generation integrated communications (mmMAGIC) and 3GPP.Differences between cluster level parameters in the LOS and non-LOS route are not significant,but the number of clusters is much smaller compared to carrier frequency below 6 GHz.Useful channel models and parameters are offered in this work for 5G radio system simulations and design at 39 GHz.关键词
