Abstract

In response to the demand for Unmanned Aerial Vehicle（UAV） networking communications

we obtain the advantages of diversity gain and communication quality improvement by using the Multi-input Multi-output（MIMO） technology.We construct a model for UAV cooperative communication system and present a cluster algorithm for MIMO collaborative transmissions.Then we conduct theoretical analysis of the Signal to Interference and Noise Ratio（SINR） in the course of communication and come to know that it can effectively improve the SINR in collaborative transmissions as compared with single node transmissions.Finally

we verify the correctness of the analysis by simulation in the model and simultaneously simulate the synchronization technology embedded in the cluster algorithm

effectively solving the problem of Inter-Symbol Interference（ISI）.
