基于国产芯片的软件无线电设备设计与实现

With the rapid development of communication technology, Software Defined Radio (SDR), as an emerging technology, has received great attention due to its flexibility and broad application prospects. This article introduces a software radio device design based on domestic chips, aiming to provide an economically effective solution for spectrum sensing and analysis in the FM frequency band. This design is based on CH32V307VCT6 as the core processor, combined with TEA5767 module to achieve spectrum scanning and analysis, and also has basic FM radio functions. It provides a user interaction interface through a 1.44-inch TFT screen. Through practical testing, the effectiveness and practicality of this design have been proven, providing a reference and application foundation for the subsequent development of software defined radio equipment.
