摘 要
随着信息技术和互联网的快速发展,教育模式正从封闭式的校园教育向开放式的网络教育转变。网络教育已成为教育新手段、新模式,是教育面向现代化的必经之路。近年来网络课件迅速发展,成为课堂教学的重要辅助手段.制作移动通信网络课件,能弥补现代通信原理课程传统课堂教学方式的不足。网络课件的高度模块化,使教师用它可以灵活地组织教学,学生用它可以灵活地选择学习,与"教无定法,学无定法"的规律相适应,是推进素质教育的现代化的教学辅助工具。
本论文包括两个方面的内容:移动通信网络课件的制作和基于Matlab的网络课程实验设计。
网络课件版面制作主要采用是基本的HTML网页形式,网页制作主要用的是FrontPage,并用MathML实现了公式与字体的不匹配问题。本论文首先介绍了网络课件概念和simulink软件的基本模块,然后介绍二进制频移键控(2FSK)、二进制相移键控(2PSK)、最小移频键控(MSK),高斯最小移频键控(GMSK)信号的调制解调原理和多经衰落原理,主要工作是用simulink模块构建仿真模型,并对这几种数字信号的仿真波形进行分析。

The develop of modern information technology and Internet ,the mode of education has been changing from close campus education to open network education. Network Education has become a new means of education networks, the new model is the way modern education. In recent years,Web-Based Courseware develops very
rapidly and become an important assistance to course teaching. The network multimedia courseware for Mobile Communication is constructed to assist the course teaching. The network is the highly modular software, through which teachers can organize teaching, and students can choose learning flexibly. And accommodating with the disciplinarian of "No way to teach and learn no way", it is a modern teaching tool with it to promote quality education.
This thesis mainly contains two parts: the process of making the Web-Based Courseware and the process of designing the Course Experimentations using MATLAB.
The website interface is constructed using the basic HTML webpage form,The design of webpage mainly uses Macromedia FrontPage, and using MathML to achieve formula with fonts not matching problem. The website interface introduces concept of the Web-Based Courseware and the basic module of the Simulink, then introduces the two of the modulation and demodulation of 2FSK, 2PSK,MSK,GMSK and the principle of Multi-track decline, the main job is using Simulink to construct simulation module, and analyzing from both time domain and frequency domain, and finitely analyze the capability of their resist noise.
