摘要
DS/FH混合扩频系统集中了直接序列扩频和跳频的优点,通信隐蔽性好、抗干扰能力强,尤其适合于军事上的应用。文中介绍了一种使用USB接口实现主机控制FPGA程序产生DS/FH扩频信号源的方法,主要内容涉及硬件电路、FPGA程序、USB固件及主机控制程序的设计;该信号源的成功研制对DS/FH混合扩频技术的应用做了有益的工作。
DS/FH hybrid communication system has incorporated all the advantages of DS and FH, its hidden and anti-interference performance is particularly suitable for military application. This article proposes a method, which generates DS/FH source by FPGA controlled by a USB interface, and primarily involves the circuit, FPGA program and USB firmware. The successful design and realization of the signal source is a valuable work for the application of DS/FH hybrid spread spectrum technology.
