摘要
介绍了跳频通信系统的基本组成、工作方式以及跳频通信系统中跳频综合器的设计要求。结合跳频综合器的设计要求以及AD9854、FPGA的特点给出了一种基于AD9854的高速跳频源实现方法,在微处理器和FPGA的控制下能够生成多种跳速和多种图案的跳频信号,适合于多种应用场合。
The paper introduces the composition and the operation mode of frequency hopping （FH） communication system and the design requirement of frequency hopping synthesizer. According to the design requirement of frequency hopping synthesizer, an implementation method of a high speed frequency hopping synthesizer based on AD9854 is introduced in this paper. Multi-pattern frequency hopping signal with multiple hopping rates can be generated under the control of CPU and FPGA. This design is applicable in many situations.
