摘　　要：设计一个基于FPGA的基带信号码发生器。首先简要介绍了单极性非归零码、双极性非归零码、单极性归零码、双极性归零码、差分码、交替极性码、分相码、传号反转码等8种基带码的基本特点,然后根据码型转换原理设计发生器模块。程序采用VHDL进行描述,并用Modelsim软件仿真实现所有功能,最后将功能集成到FPGA上,产生的基带码稳定、可靠,可满足不同数字基带系统传输需要。This paper designs a code generator of baseband signal based on FPGA. First,it introduces the basic features of eight codes,including NRZ codes, RZ codes, difference code, AMI code, Manchester code and CMI code. Then designs the generator model according to the principle of code transform. All programs are given by VHDL,stimulates the functions with Modelsim successfully. Finally,all functions are integrated on the FPGA, makes the codes stable and reliable which meet the needs of the digital baseband system transformation.
