| 摘 要： | 建立了一种新的DQPSK扩频调制解扩解调融合设计算法，并通过声表面波（SAW）匹配滤波器与声表面波延迟线解扩解调器实现了基于这种融合设计的DQPSK扩频调制器和相应的解扩解调器，为系统数据恢复、时钟提取、载波恢复以及系统的跳频同步提供了实时高信噪比信号，最后给出了验证系统的实验结果。

| Abstract: | A new DQPSK spread spectrum modulation and despread spectrum demodulation fusion designing method was introduced in the paper.The DQPSK spread spectrum modulation and relative despread spectrum demodulation based on the fusion designing method were realized by SAW matched filter and SAW delay line despread spectrum demodulator.The real-time signal with high signal noise ratio was provided to system data recovery,clock recovery,carrier wave recovery and system jump frequency synchronism.At last,the experimental result was given in testing system. |
