摘要
短波通信是唯一不受网络枢纽和有源中继体制制约的远程通信手段,广泛应用于电报、电话、低速传真通信和广播等。短波信号是构建短波通信环境的基础,对研制短波通信设备和模拟电磁环境具有重要意义。给出采用AD9856设计的基于正交调制方法的短波信号发生模块,可为研究短波通信和模拟电磁环境提供借鉴。
Shotwave communication is the only telecommunication way which is unlimited by network hud and active relay systems. It is widely applied in telegram,telephone,low-speed fax communication and broadcast.Shotwave signal is the base of communication environment.It is important to develop shortwave communication equipments and simulate electromagnetic environment.This paper discusses shortwave signal modules based on quadrature modulation method which is designed by using AD9856.In order to research shortwave communication and simulate electromagnetic environment,The module provides some reference.
