摘要
基于软件无线电的应用背景,设计了一种采用FPGA实现的DQPSK调制解调系统。重点介绍了采用Verilog HDL设计DQPSK差分编解码,以及锁相环法实现载波同步。给出了采用系统生成器建模实现和仿真。
Design a DQPSK modulation and demodulation system based on the application background of soft radio,which can be implemented through adopting FPGA.It mainly focus on the differential coding-decoding and carrier synchronization of DQPSK,which separately use the design of verilog HDL as well as the phase locked loop.Moreover,the imple-mentation and simulation using system generator are given.
