Abstract
Modulation is an important foundation of various communication systems and is widely used in fields such as broadcasting,television,radar,and measuring instruments.It plays an important role in the process of spectrum shifting.This paper studies the signal processing method based on STM32F407 single-chip microcomputer and FPGA chip,and designs a high-performance,high-precision,low-cost,and fast computing speed signal modulation method identification and parameter estimation device.According to experimental testing,the device can measure signal frequencies ranging from 1 to 30 kHz and amplitudes ranging from 30 to 100 mV.The demodulation display modulation coefficient of about 0.01,a modulation signal frequency of about 0.05,and a maximum frequency deviation of about 200 Hz.This signal device can accurately obtain measurement results,improving information transmission rate and accuracy.关键词
