RECOGNIZATION OF MODULATION SYSTEMS IN COMMUNICATION

摘要: 通訊調(diào)制體制辨別是現(xiàn)代電子偵察中經(jīng)常遇到的一個(gè)問題,本文針對(duì)現(xiàn)今通用的調(diào)制體制,提出了一種方法,這種方法只需利用截獲的一段典型信號(hào),就可以確定它的調(diào)制體制和主要參數(shù).文中給出了這一方法的理論基礎(chǔ)、具體算法和實(shí)驗(yàn)數(shù)據(jù),理論和實(shí)驗(yàn)結(jié)果表明,這是一種行之有效的方法。

Abstract: Recognization of modulation systems is an important problem in the modern electronic reconnaissance. A general method for solving this problem is suggested. From a segment of a captured signal, the modulation system can be determined, and its parameters can be extracted by using this method. The theoretical basis, algorithms and test results of this method are described. It is proved that the method is very effective in practical situation. -
