为提高无线自组网的传输距离,提升其市场应用价值,引进5G通信技术,设计研究无线自组网自适应调制方法。首先,假定无线自组网下每一个节点都有一个唯一的身份标识号码(Identity Document,ID),根据节点的传输与通信能力,建立无线自组网节点信息传输函数,设定5G通信下无线自组网节点信息传输协议与格式;其次,引进Xilinx IP Core,进行节点的调制编码;最后,进行自由空间传输时,计算无线自组网单跳链路对于信号的接收功率,以此为依据,设计无线自组网传播信号信噪比计算与自适应调制。实验结果证明,使用设计的方法进行无线自组网自适应调制可以有效提高无线自组网的通信与信号传输范围。

In order to improve the transmission distance of wireless Ad hoc network and enhance its market application value,5G communication technology is introduced to design and study the adaptive modulation method of wireless Ad hoc network.Firstly,it is assumed that each node has a unique Identity Document(ID)under the wireless Ad hoc network,and according to the transmission and communication capability of the node,the information transmission function of the wireless Ad hoc network node is established,and the information transmission protocol and format of the wireless Ad hoc network node under 5G communication is set;secondly,Xilinx IP Core is introduced to carry out the modulation of the node.Finally,the signal-to-noise ratio calculation and adaptive modulation of the wireless Ad hoc network propagation signal are designed based on the calculation of the received power of a single-hop link of the wireless Ad hoc network for signal when free-space transmission is carried out.The experimental results prove that the adaptive modulation of wireless Ad hoc network using the designed method can effectively improve the communication and signal transmission range of wireless Ad hoc network.
