基于FPGA的模拟调制器实现

The implementation of anolog modulator based on FPGA

给出了一种基于软件无线电利用FPGA实现的模拟调制器实验模块的设计方法。介绍了FPGA实现AM调制器的原理，并在DDS基础上，给出了FM凋制器的实现方法。最后对系统功能和性能进行了测试，测试结果满足设计要求。该实验模块是一个基于单片机与FPGA的综合开发实验平台。

This paper presents a design of anolog modulator experimental module based on software defined radio with FPGA. The basic principle of AM modulator is first introduced. Then, the FM modulator method is given. Finally, the functions and performance of system are tested, and the resuhs validate the approach. The experimental module is a comprehensive experimental platform based on MCU and FPGA.
