FPGA-based Gaussian waveform generation method and system

The invention relates to an FPGA-based Gaussian waveform generation method and system, and belongs to the technical field of digital information processing. According to the invention, the FPGA devicedigital synthesis mode is utilized, the clock frequency of an IP core of the FPGA is adjusted according to the center frequency of the Gaussian waveform to be generated to generate the pulse waveformwith the required frequency, a DAC module in the FPGA generates the Gaussian waveform according to data of points required by the Gaussian pulse waveform and the generated pulse waveform, and the generation of the Gaussian waveform is realized. Compared with Gaussian signals generated by a simulator, waveform trailing generated by the method is very small or even does not exist, the higher repetition frequency can be achieved due to a high-speed transmission interface and a high-update-speed transmission interface of the FPGA device, the frequency change of the waveform can be achieved only through software, and the o
