基于FPGA的数字通信系统信道编译码器的设计

Design of Channel Encode and Decode Based on FPGA in Digital Communication System

本文主要依靠FPGA平台利用VHDL语言设计数字通信系统的编译码系统。通过在QuartusII7.2上用软件编程实现汉明码编译码、DPSK调制解调等功能,并进行时序仿真验证其逻辑功能,充分体现了FPGA开发周期短、程序修改更新方便和自上而下设计流程等优势,对于其他同类型的设计开发具有指导意义。

A FPGA-based channel coding and decoding system is designed by VHDL in this paper. The function of hanmencoding /decoding and DPSK modulation/ demodulation is realized by the software of QuartusII7.2, which is proved its logic by timing simulation. It embodies the advantages of FPGA development and design： the period of development is short, the revise and update of program is convenient, top-down design process and so on. It provide guide for other similar design.
