Channel Modeling for Massive MIMO System
Currently, massive MIMO technology is regarded as the core technology of 5G mobile communication system，next generation Wifi, B5G (beyond 5G) or even 6G (6th Generation) mobile communication system. Based on wireless mobile communication system, wireless mobile channel modeling is the most important part for massive MIMO system. In this talk, the channel of MIMO system of few antennas (less than 10 antennas) is firstly analyzed. After extending the number of antennas of the proposed MIMO system channel model to a large number (tens or even hundreds), a three-dimensional geometrical channel model for massive MIMO system is established and the polarization characteristic to massive MIMO system is implemented. The proposed model includes a variety of communication environment and antenna parameters, which also has low complexity and is easily adjusted according to the communication environment.
