| 摘 要： | 文中提出了一种新型混合跳频通信技术,该技术结合传统跳频技术和差分跳频技术,在较窄的频带上采用差分跳频调制,并将该调制信号与另一更宽频带内的慢跳频信号进行混频,最终得到一个跳速高、频带宽的调制信号。接收端解调时,先按照传统跳频解调的方式进行慢跳频的解调,再按照差分跳频解调的方式对信号进行差分跳频解调。这种混合跳频通信技术在提高数据传输速率的同时,也可以很好地改善系统的误码率性能和抗单音干扰性能。

| Abstract: | A new combinable frequency hopping technology was iniroduced.This technology is to combine the traditional frequency hopping technology with the differential frequency hopping technology.The information is firstly modulated at a narrow band adopting differential frequency hopping modulation,and then mixed with another signal adopting frequency hopping modulation.After being transmitted through the channel,the frequency mixing signal arrives at the receiver.As in the transmitter,the signal is firstly demodul... |
