级联编码的同步瞄准干扰算法研究
|
摘要
现代通信广泛采用级联编码作为抗干扰措施,以保证通信质量。级联编码种类很多,其中RS编码和卷积编码的级联编码较为常用。针对级联编码的特点,提出一种高效干扰算法——同步瞄准干扰算法,对级联编码中的ASM帧同步实施干扰,从而破坏数据流的同步信息,达到阻断通信的目的。对同步瞄准方法和干扰样式选择进行深入研究。软件仿真结果表明,相比于相似信号干扰算法、扫频干扰算法、单音干扰算法和延时转发干扰算法,同步瞄准干扰算法能够对级联编码实施高效干扰。
Modern communication usually uses the concatenated code as the anti-jamming method to guarantee the communication quality. The concatenated code with RS code and convolutional code is common. According to the feature of concatenated code,this paper puts forward an efficient jamming algorithm called syn-aim jamming algorithm,which focuses jamming on the ASM frame-synchronization of concatenated code and destroys the ASM frame-synchronization data to block the communication. Furthermore,this paper studies the aim-method and jam-style deeply. Finally,the results of software simulation show that,compared with the same-signal jamming,swept jamming,single-tone jamming and delayed-forward jamming algorithms, the syn-aim jamming algorithm can achieve the efficient jamming goal against the concatenated code.
