摘要
在数字调制方式中,QDPSK有着重要的应用,是第三代移动通信系统中的W-CDMA所采用的调制方式.利用CPLD可编程芯片对QDPSK数字调制系统的码变换器进行了设计,用VHDL语言编程实现了串/并转换模块、绝对/相对码变换模块等功能.进行了软件仿真和硬件调试,得到了预期的结果.
QDPSK has an important application in the digital modulation mode,which is adopted in W-CDMA of the third generation mobile communication.The code converter of QDPSK digital modulation system is designed based on CPLD.Serial-to-parallel model and absolute-to-relative code converter model have been implemented based on VHDL.This design gets expected result through software simulation and hardware debugging.
