FPGA Implement of 64QAM Modulator Based on DDS
LI Xing-pei · Journal of Sichuan University of Science & Engineering · 2006
The quadrature amplitude modulation adapted to digital microwave system and a kind of all digital frequency synthesis technology –DDS are interpreted.The NCO design of 64QAM modulator adopts DDS technology and every module of 64QAM is carried out by FPGA.Finally,the design is simulated in QuartusⅡ5.0 software platformIt of Altera company.
