无线电台的调制解调技术研究

Research on Modulation/Demodulation Technology of Radio Station

长期以来,各种通信设备都是针对某种特定用途设定的,无论是通信体制、信息传输格式还是工作频段都各自为政。当需要进行联合通信时,由于互不兼容,设备间无法实现信息情报的快速沟通。目前无线电台的调制解调开始朝软件化方向发展,其优点在于可以在通用的硬件平台上,使用不同的软件来实现不同的信息传输格式和通信体制,通过软件的更新来实现电台的交互通信。文中主要对无线电台的调制解调技术进行研究,为无线电台的软件化发展提供参考。

Over the years,various communication devices are designed for particular purposes,and they have differ-ences in communication system,information transmission format and operating band.When in need for joint communica-tions,due to incompatibility,fast communication of information and intelligence among devices can not be achieved.With the development of radio technology,the modulation/demodulation of radio station starts to utilize software,whose advan-tages are that former hardware incompatibility can be got over by using different software on the universal hardware plat-form to achieve interactive communication.In this article,modulation/demodulation technology of radio station are mainly studied,which can provide reference for the development of radio station using software.
