Ultra-Massive multiple input multiple output technology in 6G

6G was the current research hotspot. Through the analysis of UM-MIMO system model, frequency interleaving and antenna mapping, physical layer and link layer, combined with UM-MIMO channel matrix model, through the simulation ofUM-MIMO system based on array of subarray, the corresponding relationship between system capacity and signal-to-noise ratio was obtained, namely, improving signal-to-noise ratio can effectively improve system capacity, so as to guide network site planning.
