Abstract

The invention discloses a triple non-stationary wireless communication channel modeling method under space-time consistency, which organically integrates a low-complexity parametric method and a high-precision geometric method by capturing smooth and consistent evolution of clusters in an environment in a space-time domain and path gains related to modeling frequency. Smooth and consistent cluster evolution, soft switching of cluster power and effective modeling of frequency-related path gains are realized, the problem that an existing channel model cannot model space-time-frequency non-stationary characteristics of a channel under space-time consistency is solved, and the accuracy and universality of constructing the channel model are improved. The statistical channel model under the millimeter-wave large-scale MIMO high-dynamic scene, which is constructed by adopting the method disclosed by the invention, has the characteristics of high accuracy, simplicity and feasibility, can support reasonable design and performance analysis of a communication and inductance integrated system, and meanwhile, provides a real and reliable simulation verification platform for a wireless communication network system-level algorithm.
