摘要 针对常规扩频通信系统PN码资源受限的局限性,给出一种基于特定相位的同步码实现系统同步的双CPSK扩频传输方案。该方案采用正交两路CPSK扩频传递信息,采用的扩频码是由一条扩频码进行循环移位而获得的子码集合构成,同步由两路相同的扩频码在相关处理时产生的高值相关峰的识别实现。仿真结果表明该方案可以准确快速实现同步,同时具有较高的频谱利用率和较好的误码性能。 To solve the limitation that conventional spread sptrum communication suffers from PN sources,a scheme of double Code Phase Shift Keying(CPSK) Spread Spectrum(SS) communication system was proposed,in which synchronization is achieved by synchronization code based on specia phase.In the system,information is transmissioned by orthogonal channels,and all SS codes come from one SS code by cyclic shifting.Synchronization is achieved by a same synchronization code which have the same special code phase in orthog...
