基于 D2D 通信和虚拟 MIMO 的飞行器集群网络传输方案设计

For the purpose of improving the performance of multi-aircraft network without applying for more resources, a transmission scheme that combines the device-to-device (D2D) communication of 5G with the virtual multiple-input multiple-output (MIMO) of relay communication is proposed, in the network that some nodes can connect directly and the path loss varies with different routes. The transmission scheme focuses on impact to signal-to-noise ratio, bit error rate and access probability which are caused by various combinations of cooperative communication protocols and distributed space time coding (DSTC). The simulated results show that the proposed transmission scheme based on D2D and virtual MIMO's combination can effectively improve the performance of multi-aircraft network without adding the resources, and the distributed space time coding is introducing to further optimize the performance of bit error rate. And the improvements of evaluating indicators of 3 transmission protocols are different.
