| 摘 要： | 数字通信系统通常采用前向纠错编码提高系统可靠性,传统干扰方法针对采用前向纠错编码通信系统的干扰效果较差,为了克服此缺点,提出了通过控制错误分布的脉冲干扰方法。分析了典型卷积码和RS码的纠错能力,根据2种纠错编码的特性分别探讨了干扰信号设计原则和方法。计算机仿真表明,针对不同的编码样式采用特定脉冲干扰参数,能够取得更好的干扰效果。

| Abstract: | The forward error correction coding is used widely to improve the reliability in digital communication systems.The traditional method of jamming is less effective for communication systems using forward error correction code.The error-correcting capability of convolution code and RS code is analyzed first.Based on the characteristics of error-correcting codes,the design principles and methods of jamming waveforms are explored.The results of simulations show that the optimal jamming effect can be obtained when pulse jamming is used with certain parameters exerted on different codes. |
