Abstract
The MIMO technology and antenna configuration is analysed and suggested, which has helped to meet the tremendous growth of the increasing mobile broadband demand, and implements diversity using clustered array antenna elements with a fixed spacing to obtain radiation patterns and gains. The structure of the antenna output of the transceiver in the smart antenna is described, and the simulation and measured results for the smart antenna system and massive MIMO technology on the plane structure is presented. The SISO and MIMO system structures are compared, and the electric field pattern and antenna gain are obtained by assuming the antenna array in the planar massive MIMO, and the capacity of the MIMO channel according to the signal-to-noise ratio was analyzed as a cumulative distribution function. A theoretical overview of the smart antenna system and large-capacity MIMO is presented, and the implementation strategy of the simulator related to the mentioned technology is described. Using one of the widely used open source network simulators, it presents several functions that expand the basic functions provided by the simulator, and proposes a method of appropriately implementing the existing simulation equipment suitable for 5G wireless network communication environments. When the number of transmitters is fixed, the number of receivers is changed to analyze the change in channel capacity. A development platform for a MIMO system and a smart antenna was presented, and a method of improving the signal-to-noise ratio in the receiver and increasing the capacity of the mobile wireless system through this technology was presented.
