An Anti-interference Method of Communication Based on Iteration of Multi-state Distribution in Hidden Layer

通信系统中的抗干扰设计是系统在强干扰环境下正常通信的重要保障,提出一种引入多状态隐层分布迭代的通信抗干扰方法,在通信系统中,首先对数据进行多状态的分布特性计算,分析通信数据的规律,然后对多状态的隐层分布进行统计分析,引入不断迭代更新,提取系统的噪声特性,然后对噪声和真正的通信数据进行分离,从而实现通信抗干扰方法.最后采用一组实际的通信数据进行试验,强干扰下,试验结果显示,引入多状态隐层分布迭代的通信抗干扰方法,系统通信的误码率降低到了1.2%,基本不影响正常通讯,系统具有很好的应用价值.

The anti-jamming design of the communication system was an important guarantee in a strong interference environment. An anti-interference method of communication was proposed based on iteration of multi-state distribution in hidden layer, the data for the multi-state distribution characteristic was calculated firstly, and then the laws of communicationdata was treated with algorithm, then the hidden layer multi-state distribution was done for statistical analysis, based on iterative updating, the noise characteristics of the system was extracted, and then the noise and signal was separated. Finallya set of data was used to test the actual communication in strong interference, the test result shows that with iteration ofmulti-state distribution in hidden layer, the communication error rate was reduced to 1.2%, it does not affect normal communication, and the system has a good value for application.
