| Abstract: | 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. |
