摘    要:从短波数传中载波同步问题的分析入手,提出了一种稳健的软件载波同步方法。详细地编写了算法过程并作了主要性能分析,得知其速度及精度均能达到高质量数传的要求。此方法应用简便可靠,能在较强干扰下工作。对于中、低速数传,此方法可直接用作载波同步,而对于高速数传则可作为有效的载波预同步措施以改善误码性能。

关 键 词:短波数传,短波通信,载波同步,鸟声Z变换,软件方法

Abstract:This poper puts forward a robust method with pure software for carrier synchronization. Thepredures of an algorithm are worked out in detail and the performances are analyzed. It shows that thespeed and accuracy are all satisfied for high quality HF modem. The method is reliable and quite simple andmay be used in strong interferece. This method may be used for carrier Synchronization in lower or mediummodem directly,and in high speed HF modem,this method may be used as carrier presynchronizing methodeffectively,so its error rate property may also be highly improved.
Keywords:HF modem  short wave communieation  carrier synchronizing  chirp Z transform  software method
