摘要：在无中心飞行器集群网络中,非直通条件节点间不同的中继路径可能导致较大路径损耗落差,为有限资源前提下网络传输能力的提升带来困难。参考5G移动通信中的终端直通(Device to Device,D2D)技术与中继通信中的虚拟多输入多输出(Multiple-Input Multiple-Output,MIMO)技术,提出一套D2D通信与虚拟MIMO技术结合的无中心飞行器集群网络传输方案。重点研究在正交资源模式下,将不同的协作传输协议与空时编码进行组合,在信噪比、误比特率、接入概率等方面对通信性能的影响。仿真结果表明:D2D通信与虚拟MIMO技术结合的传输方案在不增加资源的前提下,对集群网络的通信性能有明显提升,且引入分布式空时编码可进一步优化误比特率性能,但3种传输协议在不同传输质量评价方向的改善有所不同。

摘要：Since a typical mammalian cell contains only 200–300 picograms of proteins and the lack of a proteome amplification strategy[1],a practical and high-throughput approach for single-cell proteomics has long been awaited.A series of methods have been explored to make single-cell proteomics *** design of nanoPOTS and OAD chip-based processes minimizes sample preparation steps and volumes to reduce sample loss[2,3].
