| الوصف: | Recently, a measurement campaign for characterizing the channels in underground subway environments was conducted in Shanghai, China. Downlink signals transmitted by 46 universal mobile telecommunication system cells deployed along a 34-km-long subway were collected. Channel impulse responses are extracted from the data received in the common pilot channels, based on which parameters of multipath components are estimated by using a high-resolution parameter algorithm derived using the space-alternating generalized expectation-maximization principle. Multiple time-evolving clusters are obtained, each representing the channel from a remote-radio-unit of a base station to the receiver. Based on a total of 98 time-evolving clusters, channels observed in the station scenario and the tunnel scenario are modeled separately for their distinctive behaviors in many aspects, particularly in the variations of clusters' trajectories. Intracluster characteristics parameterized by cluster delay and Doppler frequency spreads, K-factor, and dependences among these parameters are investigated. Intercluster parameters, including coexisting cluster number, delay offset, power offset, and cross correlations, are investigated for the station scenario. A path loss model is established for the tunnel scenario. ; national Natural Science Foundation of China (NSFC) [61471268, 61571020]; national NSFC key program [61331009]; National 863 Project [2014AA01A706]; Major Project from Beijing Municipal Science and Technology Commission [D151100000115004] ; SCI(E) ; EI ; ARTICLE ; caixuesong@tongji.edu.cn; yinxuefeng@tongji.edu.cn; xiangcheng@pku.edu.cn; antonio.perez@upm.es ; 8 ; 3563-3575 ; 64 |
