Sheng Xiang-zuo · Telecommunication Engineering · 2007
According to the development of the full digital design in modern communication systems and extensive applications of FPGA,this paper proposes a new implementation scheme of full digital QPSK modulator with FPGA,which is based on DDS technology.Finally the correctness and feasibility of the scheme are validated through software simulation and hardware testing.
