保密和抗干扰通信是人们十分感兴趣的课题。图1和图2就是二种保密通信的示意图,二种系统是很相似的。当其噪声状的数字序列产生后就以二进制方式加到数据输入端,而后在接收端产生一个完全相同的数字序列并叠加到接收信号上,重新产生输入数据。 Confidentiality and anti-jamming communication is a topic of great interest to people. Figure 1 and Figure 2 are two kinds of secure communication schematic, the two systems are very similar. When the noise-like digital sequence generated after the binary input to the data input, and then the receiving end to produce an identical sequence of numbers and superimposed on the received signal, re-generate the input data.
