| Abstract: | The paper proposed a high -performance QPSK digital modulator ' s implementation method based on FPGA, Altera NCO2.3.0 offers high-stabilization digital sine signal for QPSK, the imitation and experiment of FPGA design were given. The experi-ment result shows, the SFDR and SNR of QPSK modulator is greatly enhanced based on NCO,effectively reduced the hardware cost, the QPSK modulator work stably and reliable,satisfies the design request. |
