中文摘要：

本文以“数字通信”课程中的难点：信道解析为例,融入“线性代数”和“信号处理”等相关课程的知识内容,设计了一种递进式探究教学方法和课程实践方案。并以推导互扰条件下的信道分解公式为例,来完成探究式课程内容的学习与互动。教学实践表明,该方法能针对本学科特点,提高教学质量。

英文摘要：

The paper presents one teaching method for the key knowledge point in the Digital Communication course： channel analysis, which used the combination with the knowledge of Linear Algebra and Signal Processing courses. The layer upon layer progressive method could realize the interaction based on the derivation of crosstalk channel decomposition formulas. The results show that the method could improve the teaching quality, and help the student to achieve the key points.
