Description
technical field [0001] The present disclosure relates to the communication field, and in particular to a non-stationary channel modeling method and device for a vehicle-to-vehicle multi-antenna system. Background technique [0002] In recent years, massive MIMO (multiple-input multiple-output) multi-antenna wireless communication technology has become the focus of research because of its advantages of greatly improving spectrum efficiency and system capacity. Meanwhile, vehicle-to-vehicle (V2V) communication is considered to be one of the indispensable parts of intelligence. Therefore, considering the use of MIMO multi-antenna wireless communication technology in the V2V communication system (the V2V communication system using MIMO multi-antenna wireless communication technology is referred to as vehicle-to-vehicle multi-antenna system in this paper), for the fifth generation wireless communication network (5G is very helpful. Existing related literatures have given geomet...
