| 摘 要： | 将全数字接收机的结构引入到扩频接收机中,用一种前向的并行处理结构来代替传统码延迟锁定环的反馈结构,采用差分相干积累的方法捕获低信噪比扩频信号的伪码相位.仿真结果表明,这种方法能快速可靠地捕获低信噪比扩频信号的码同步,可以应用于开环的全数字扩频接收机中.

| Abstract: | The architecture of all digital receiver is introduced into spectrum spread receiver in which a forward parallel processing architecture is adopted instead of the feedback,and a difference coherent accumulating method is adopted for capturing the phase of PN code with low SNR.The simulation result shows that the method can capture reliably the synchronization of PN code of low SNR spectrum spread signal and may be applied in all digital spectrum spread receiver with open-loop architecture. |
