摘　　要：介绍了基于2ASK,2FSK,BPSK,MSK和64QAM等多种通用调制器的调制原理,并提出了一种基于DDS技术的调制方式,然后在DSP Builder上进行系统设计与仿真,经验证该系统可以成功实现多模式信号调制功能,并且具有较好的可扩展性和灵活性。最后用FPGA实现,并用SignalTapII进行硬件验证。The theory of general modulator based on 2ASK, 2FSK, BPSK, MSK and 64QAM is introduced, and a method of modulation based on DDS technology is proposed. Then systematic design and simulation are implemented based on DSP Builder. The test results show that the proposed system can serve as multi-mode modulator, and the system has a great extensibility and flexibility in signal modulation. Finally, the proposed system is realized based on FPGA and tested by SignalTapⅡ.
