Design of QDPSK Digital Modulation Code Converter Based on CPLD
Lina Zhang · Journal of Inner Mongolia University · 2010
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.
