Design and Implementation of a Universal Modulation Platform Based on FPGA and AD9957

文中提出了一种以FPGA和AD9957为核心的通用调制平台的设计方案,并给出了此方案的具体实现。该方案结构简单,控制灵活,可以通过配置不同的软件实现所需的调制信号,即可对数字信号进行调制,也可对模拟信号进行调制;既可以采用FPGA内部信号源,也可外接信号源。另外,文章还给出了AM调制在该平台的具体实现方法及其结果。

This paper presents a universal modulation platform in which FPGA and AD9957 is the core of the platform. The structure of this platform is simple and has flexible control. It can configure different soft- wares to implement the desired modulated signal. Both the digital signals and the analog signals can be modulated on this platform. In addition, the platform can employ either a FPGA internal signal source or an external signal source as its signal source. In addition, an AM modulation signal which shows the concrete implementa- tion on the platform is presented.
