摘　　要：高速率跳频、高带宽技术是提高跳频发射机性能的关键,本文结合软件无线电思想和架构,提出一种基于FPGA+DSP的跳频电台传输系统的设计方案,该系统兼容多种调制方式和跳频速率及数码率。系统采用上下变频器作为系统基带信号与中频信号之间的频率转换器,还给出了系统电路原理图和程序流程图。How to achieve high speed frequency hopping and high bandwidth is key to improve the performance of frequency hopping transmitters. This paper provides a hopping radio transmission system based on FPGA＋ DSP design. This system is also compatible with a variety of modulation, frequency of hopping and data rate. An up/down converter is used as the frequency converter between IF signal and baseband signal, and the circuit schematic and software flowchart of the system are provided.
