| 摘 要： | CCSK码字的同步不同于DSSS系统的PN码同步．他的实现不适合采用DSSS系统的序贯检测法;“多码字相关平滑匹配”法相对于序贯检测法具有明显的优势是CCSK信号盲检测中实现码字同步的一种快速有效方法。

| Abstract: | Code synchronization of Cyclic Code Shift Keying (CCSK) is different from the Pseudo Noise code (PN) synchronization of Direct Sequence Spread Spectrum (DSSS) system. The method of sequential search used in direct sequence spread spectrum system is unfit for the code synchronization of cyclic code shift keying. The method of "Multicode correlation smoothing matching" has distinct predominance over the method of sequential search, it is a great efficiency and speed method for the code synchronization in cyclic code shift keying signaling blind detection. |
