“现代信号处理”中小波变换案例教学探索与实践

Exploration and Practice of Case Teaching on Wavelet Transform in “Modern Signal Processing”

摘要: “现代信号处理”是电子与通信工程、信息与通信工程等专业研究生的一门重要专业基础课。针对《现代信号处理》中小波变换知识板块教学面临的问题，提出了小波变换的案例教学法。本文先介绍了小波变换案例教学的课程设计方案，然后对理论知识讲授、典型案例分析、翻转课堂等各环节教学内容进行了详细阐述。通过引入实践案例与翻转课堂教学形式，提高了研究生课堂参与度，培养了研究生的自主学习能力、知识应用能力与工程实践能力。

Abstract: Modern Signal Processing is an important foundational course for graduate students majoring in Electronic and Communication Engineering, Information and Communication Engineering, and other related fields. In response to the problems faced in teaching the section of wavelet transform in Modern Signal Processing, a case teaching method is proposed. The article first introduces the course design scheme of wavelet transform case teaching, and then elaborates on the teaching content of various links such as theoretical knowledge teaching, typical case analysis, flipped classroom, etc. By introducing practical cases and flipped classroom teaching methods, the participation of graduate students in the classroom has been improved, and their self-learning ability, knowledge application ability, and engineering practice ability have been cultivated.
