Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an adaptive transmission method and device for a MIMO-FBMC system. Background technique [0002] In the research on 5G wireless communication in recent years, massive MIMO (Multiple Input Multiple Output) technology plays an important role in increasing the capacity of multi-user network systems. In a typical dense urban communication network scenario, most of the data traffic is generated through a highly concentrated user group, and a possible solution to the data demand is to use massive MIMO technology and large-scale antenna arrays to meet the capacity and speed requirements of the 5G system. to an important supporting role. The key technology in the 5G system is the new multi-carrier technology, and the FBMC (Filter Bank Multi-Carrier) technology in the new multi-carrier technology has become the focus of 5G communication network research because it ...
