As a widely acknowledged efficient and green transport model, rail traffic is highly expected to evolve into a new era of “smart rail mobility” where infrastructure, trains, and travelers will be interconnected to achieve optimized mobility, higher safety, and lower costs. Therefore, a seamless high-data rate wireless connectivity and up to dozens of GHz bandwidth are required. Such a huge bandwidth requirement motivates the exploration of the underutilized millimeter (mm) and sub-mm wave bands. As the benefits of the mm/sub-mm wave systems are directly related to the propagation environment and antenna arrays, realistic channel models are of great importance. This research project is aimed at gaining a deep expertise and advancement of the state-of-the-art in the mm and sub-mm wave mobile channel characterization and modeling. Propagation mechanism constitution, frequency dispersion of ultra-broadband channel, and channel dynamics – spatial-temporal Doppler properties – introduced by moving objects and transceivers, are three open challenges that inhibit the realization of mm/sub-mm wave communications in rail traffic scenarios. To begin with, the propagation mechanisms will be identified for 8 GHz bandwidths in 60 GHz and 300 GHz bands, taking into account the main objects in rail traffic scenarios. Moreover, with extensive measurements and simulations, the frequency-dispersion effect will be analyzed in frequency, time, angular, and polarization domains. Finally, based on the evaluation of the influence of the mobility and the variation of mobility on the channel dynamic parameters, a stochastic spatio-temporal model will be established to provide an incentive for intensified R&D effort in the field of mm/sub-mm wave communications enabling smart rail mobility. The first channel sounder that can support mobile measurements in the 300 GHz band will be provided by the host institute. This is critical for the completion of the project. [Mehr]
