摘要
随着无线通信技术的发展,无线调制信号分析仪在无线电监测、科学化管理方面有重要的实用意义。文章基于STM32嵌入式平台,采用二次变频芯片MC13135接收并解调出调制信号,并通过FFT算法分析处理,设计实现了一套新型的无线监测管理设备。测试结果表明,该信号分析仪能够快速准确的探测无线电管理地域内的无线电信号,并能实时反馈被测信号的通信技术参数、工作特征等信息。
With the development of wireless communication technology, wireless modulation signal analyzer has an important role in radio monitoring and scientific management. Based on STM32 embedded platform, using the secondary frequency conversion chip MC13135 to receive and demodulate the modulated signal, a set of new wireless monitoring management equipment is designed, which embeds FFT algorithm to complete signal analysis. Measurement result shows that this analyzer can detect radio signal rapidly and accurately in management territory, real-time feedback the communication relative parameters and working characteristics of the measured signal.
