摘要
针对无线通信技术教学中存在的理论与实践脱节问题,设计了基于STM32的调幅信号接收机实验系统,该实验系统由硬件及软件两个部分组成,硬件部分包括低噪声放大、本振、混频、中频放大及解调等,软件部分包括本振频率设置及自动增益控制。通过搭建该实验电路,引导学生理解电路理论对实践的指导作用,培养学生分析问题与解决问题的能力,提高学生的工程应用能力。实践结果表明,该实验可大大激发学生的学习兴趣,提高无线通信技术课程的教学效果。
To solve the disconnection between theory and practice in the teaching of wireless communication technology,an experimental system of amplitude modulation signal receiver based on STM32 is designed. The experimental system is composed of two parts: hardware and software. The hardware part includes low noise amplification,local oscillator,mixing,intermediate frequency amplification and demodulation. And the software includes local oscillator frequency setting and automatic gain control. By setting up the experimental circuit,the students can be guided to understand the guiding role of circuit theory and to use it in practice. Ability of analyzing and solving problem can be cultivated;the engineering application ability is improved. The practice results show that this experiment can greatly stimulate the students’ interest in learning and improve the teaching effect of wireless communication technology course.
