UAV Cooperative MIMO Technology

In view of the UAV load data transmission, MIMO technology and cooperative communication technology are applied to the practical application of UAV. Firstly, the MIMO system and the system structure and basic principles of V-BLAST are introduced. Then the principle of MMSE detection algorithm and the influence of antenna correlation on system performance are introduced. At last, using Matlab to simulate the performance of the system under different channel correlation and different modulation methods, the changes of the performance of the V-BLAST system based on the MMSE algorithm are changed with the change of the channel correlation coefficient and the modulation mode.
