摘要
首先介绍QPSK调制的基本原理,提出了一种基于FPGA的全数字QPSK调制方案。本文重点介绍了QPSK数字调制系统各个子模块的设计思路和流程,并对QuartusⅡ软件进行简单介绍,通过QuartusII软件对各子模块和顶层文件进行综合和仿真,最后在基于stratixⅡ系列芯片EP2S30F672C5的PCB板上证验了本设计的正确性和可行性。
This paper first introduces the basic principles of QPSK modulation, and proposes a FPGA-based all-digital QPSK modulation scheme. This article focuses on the QPSK digital modulation system sub-module design and process, then give a brief introduction of Quartus Ⅱ , through the various Sub-module modules and top-level document simulation, and verify the correctness and feasibility of the design in the PCB board based on stratix Ⅱ series chip EP2S30F672C5.
