摘　　要：现有无线通信信息安全传输方法存在安全隐蔽率较低的问题,因此,文中设计了一种基于空频联合加扰的无线通信信息安全传输方法。量化无线通信信道特征,改进中继节点转发模式,获取相应的分集增益,基于空频联合加扰提取载波因子,根据似然准则,计算在第n个载波上发送的通信信息的可接收SNR,识别无线信道幅度的衰落变化规律,设计信息安全传输方法。实验结果:本文设计无线通信信息安全传输方法的安全隐蔽率均值为67.111%,说明在结合空频联合加扰算法后,文中的无线通信信息安全传输方法隐蔽性更高。The existing wireless communication information security transmission methods have the problem of low security concealment rate.Therefore,a wireless communication information security transmission method based on space frequency joint scrambling is designed.quantize the characteristics of the wireless communication channel,improve the relay node’s forwarding mode,obtain the corresponding diversity gain,extract the carrier factor based on the space frequency joint scrambling,calculate the acceptable SNR of the communication information sent on the th carrier according to the likelihood criterion,identify the fading law of the wireless channel amplitude,and design the information security transmission method.Experimental results:The average security concealment rate of the wireless communication information security transmission method in this design is 67.111%.This shows that the security concealment of the wireless communication information security transmission method in this paper is higher after combining the space frequency joint scrambling algorithm.
