| 摘 要： | 作为提高通信系统抗干扰能力的重要方式，扩频技术意义重大。和经典的直接序列扩频DSSS相比，CCSK软扩频方式出现较晚，但也在某些场合得到了应用，譬如在JTIDs系统中。文章基于JTIDS系统，对DSSS和CCSK编码进行了仿真，并比较分析了二者的抗干扰性能，在假设已经取得载波和位的同步的前提下，得出了在小错误率情况下CCSK编码性能优于DSSS编码，但在大错误率情况下CCSK编码性能劣于DSSS编码的结论。

| Abstract: | As an important method to improve the anti-jamming performance of the communication system,the spread spectrum technique is of great significance.Compared with the classical direct sequence spread spectrum(DSSS) method,CCSK software spread spectrum method appeared a bit later,but it is still applied in some occasions,especially in JTIDS system.Based on the JTIDS system,DSSS and CCSK are simulated in this paper,and their anti-jamming performances are also comparatively analyzed in detail.At last,on the premi... |
