| 摘 要： | 多相正交码是一种比二元码更优秀的地址码,而多相完全互补码具有更良好的相关特性。在分析多相正交码性质的基础上,研究基于多相完全互补码的串行时分CDMA通信系统,给出此通信系统的设计方案,方案采用自适应移位递归寄存器实现高速数据传送。并对此CDMA系统消除多址干扰影响和精确估计多径效应的性能进行详细分析。

| Abstract: | Polyphase orthogonal codes are more excellent address-codes than duality codes,and polyphase complete complementary codes have even more fine correlation properties.The serial time-sharing CDMA communication system based on polyphase complete complementary codes is studied after analyzng the correlation properties of polyphase orthogonal codes.The design of such a communication system is described.The system achieves high-speed data transmission based on auto-adaption shift recursion register.The capabilities to mitigate the multi-address interruption and estimate the multipath impact are analysed. |
