基于FPGA的单边带调制解调系统

单边带通信是目前应用比较广泛并具有占用较窄频带特点的一种通信方法。本文着重介绍单边带调制解调技术,采用DSP Builder设计流程,结合Modelsim对Signal Compiler生成的test bench文件进行仿真,在QuartusⅡ环境下编译生成VHDL语言,组建工程,下载至硬件,利用Signal TapⅡLogic Analyzer观察硬件输出波形。

FPGA-based single-sideband modulation and demodulation system

Single sideband communication is a communication method with broader application and occupying a relatively narrower band.Here we will focus on the understanding of single sideband modulation and demodulation technology.Applying DSP Builder design process,we combine with Modelsim simulation of the TestBench documents generated by Signal Compiler,and then compile VHDL language generated by Signal Compiler in the QuartusⅡenvironment,establish the project and download to the hardware. Finally,the output of the hardware was observed by Signal TapⅡLogic Analyzer.
