摘　　要：通信原理是一门具有很强物理意义的专业理论课,因其内容抽象而繁杂,给教学带来了一定的困难。基于整合教学内容的目的,本文探讨了将众多调制方式(包括模拟调制和数字调制)统一为正交调制模型的教学方案。为了在满足教学要求的前提下降低教学难度,提出了用MATLAB进行仿真演示的教学方法。教学实践证明,该教改方案不仅达到了有效整合课程内容的目的,而且通过使用信息工具将抽象知识具体化、直观化的这一途径使得教学质量得到了提高。Communication principle curriculum is a specialized theoretical course with strong physical meanings. It is both abstract and complication. Therefore, it is also difficult to teach well. For the purpose of integrate course＇s contents, a specific teaching scheme is proposed for making two modulations unification, including analogue modulation and digital modulation. In order to reduce difficulty of teaching and ensure quality of education, the method of instruction base on MATLAB simulation is applied to teaching process. Teaching practice shows that the reform not only achieved the aim of integration of course contents but also improved the teaching quality by the way of using information tools to make abstract knowledge concrete and clear.
