Research and Simulation of Optimized Method for Mobile Communication of Clustered Fighter

在集群式战斗机移动通信的过程中,mhgf直通模式导致在通信过程中会出现大量的随机干扰问题。传统的通信方法是为了解决干扰,采用了大容错的方法,但是不能很好解决容错性能和编码效率之间的矛盾,增加了通信负担。提出集群式战斗机移动通信优化方法,分析了集群式战斗机通信信号融合规则,依据战斗机视觉显著度模型的帧级、宏块级两级码率分配策略,实现战斗机视频编码码率的控制与分配,增强码率受到约束时显著度区域的主观战斗机通信信号质量,根据集群式战斗机通信信号在时域中波动稳定的性质,直接复制上一帧集群式战斗机信号对应位置的宏块,实现集群式战斗机移动通信优化。实验结果表明,通过所提方法进行集群式战斗机移动通信优化方法,可以极大的提高集群式战斗机的通信的效率,并且有效降低误码率。

In the process of mobile communication of clustered fighter,the use of direct mode operation will result in a lot of random interference problems in the process of communication. In order to solve the problem of interference,the method of big fault-tolerant was adopted in traditional communication method. However,it cannot solve the contradiction between fault-tolerant performance and coding efficiency very well,increasing the burden of communication. An optimized method for mobile communication of clustered fighter clustered fighter was proposed,in which the communication signal fusion rule of clustered fighter was analyzed. Based on the two rate allocation strategies for frame level and macro block level of fighter＇s visual significance model,fighter＇s video encoding rate control and allocation can be implemented,enhancing the subjective fighter＇s communication signal quality in significance area while the code rate was constrained. According to the properties of fluctuated stability of clustered fighter＇s communication signals in the time domain,the macro block which location was corresponding to previous frame＇s clustered fighter signal was copied directly,to realize the mobile communication optimization of clustered fighter. The experimental results show that using the proposed method for mobile communication optimization of clustered fighter,can greatly improve the efficiency of the clustered fighter＇s communication,and effectively reduce the error rate.
