摘要
通信系统的振幅键控(ASK)、移频键控(FSK)和移相键控(PSK)是数字调制的3种基本信号形式。为了提高系统的静态可重复编程和动态在系统重构的特性,采用Altera公司的DSP Builder开发软件和直接数字频率合成技术,介绍了一种基于FPGA的通用调制器的软件设计过程,整个系统便于编程、修改以及升级改进。
The three basic modulation of digital signal forms are ASK, FSK and PSK in communication system. For improving the characters of static re - programmed and dynamic reconstructing on system. In this paper, we have utilized a modern development technology of DSP （DSP Builder ） and the technology of Direct Digital Synthesizer（DDS）. The process of soft design is introduced mainly about the currency modulator based on FPGA（FieId Programmable Gate Array）,the last whole system is easy to program and modify as well as upgrade.
