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。
Anti-interference design in communication system is an important guarantee for normal communication under strong interference environment. A communication anti-interference method is proposed to introduce iterative iteration of multi-state hidden layer. In the communication system, the multi-state distribution of data Calculate and analyze the rules of communication data, and then make statistical analysis on the hidden layer distribution in multi-state, introduce continuous iterative updating, extract the noise characteristics of the system, and then separate the noise and real communication data to achieve the communication anti-jamming method. Finally, a set of actual communication data is used to test. Under strong interference, the experimental results show that the introduction of multi-state hidden layer iterative communication anti-jamming method reduces the bit error rate of the system communication to 1.2% and does not affect the normal communication. The system Has good application value.
