| Abstract: |
| According to the development of the full digital design in modem 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. |
