| 摘 要： | FM-DCSK通信系统是对DCSK系统的改进,但是由于消息信号是经发射端开关切换,跟随着参考信号发射出去的,因此会出现跳变,并且重复发送,也降低传输码率。用CDSK方案取代DCSK方案,并与FM结合,可以保留CDSK的优点,提高保密性和传输码率。

| Abstract: | Frequency-modulated DCSK is an improved scheme of DCSK. In the transmitter, the messages follow the reference signals via a switch, which results in a hopping in time domain and the repeated signals. And consequently, the bit rate is reduced. If DCSK is replaced by CDSK, for the combination with FM, the scheme can have the advantages of the CDSK, and the security and the bit rate are enhanced. |
