摘要
针对无人机组网通信的需求,利用MIMO(多输入多输出)技术可以获得分集增益、提高通信质量的优势,构建了一个无人机协作通信系统模型。提出了一种解决MIMO协作传输的组簇算法,对通信传输过程的信干噪比情况进行了理论分析,得知协作传输相比单节点传输可以有效提高信干噪比。在构建的模型下进行了仿真,验证了分析结果的正确性。同时对组簇算法中嵌入的同步技术进行了仿真,可以有效地解决码间串扰问题。
In response to the demand for Unmanned Aerial Vehicle （UAV） networking communications, we obtain the advanta-ges 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 trans-missions. Then we conduct theoretical analysis of the Signal to Interference and Noise Ratio （SINR） in the course of communi-cation 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）.
