Abstract

A 5G-oriented multi-dimensional adaptive MIMO system and a method for adjusting the radiation pattern of an antenna port, the system includes a transmitting antenna array, a first turntable, a broadband vector signal generator, a receiving antenna array, a second turntable, and a broadband vector signal analyzer and a data acquisition terminal; the broadband vector signal generator and the broadband vector signal analyzer are respectively connected to the transmitting antenna array and the receiving antenna array, and the data acquisition terminal is connected to the broadband vector signal generator and the broadband vector signal analyzer. Method By optimizing the weight vector of antenna elements, the correlation between antenna ports is expressed as the antenna element matrix and its corresponding weight vector function that constitutes the antenna port; by controlling the azimuth angle, elevation angle and antenna element The downtilt angle enables dynamic adjustment of the radiation pattern of the antenna port. The invention adopts the antenna array structure, the shape factor is more flexible, more analysis information is provided, and the spatial correlation of the system is increased.

Description

technical field [0001] The invention relates to a 5G-oriented multi-dimensional self-adaptive MIMO system and a method for adjusting the radiation pattern of an antenna port, which uses the number, position, mode and corresponding weight vector of antenna elements to control the radiation pattern of the antenna port. Background technique [0002] Massive multiple-input multiple-output (MIMO) base stations are equipped with a large number of antennas (typically tens to hundreds) for additional system gain. MIMO technology is an active area of ​​research and standardization for fifth generation (5G) wireless communication systems. MIMO technology has been the subject of people's attention in the past two decades due to its ability to cope with the growth of wireless data traffic and improve the reliability of wireless systems. From the perspective of passenger experience, in addition to the requirements of 5G, the next-generation transportation systems of high-speed railways,...
