The important carriers that the multimedia teaching courseware educated as the modern multimedia, its abundant expression, good interaction and great sharing, Will inevitablely play a bigger role in our study and life in the future; Meanwhile, in the future information-intensive society, as the support technology of the information-intens society, Moving communication will get greater development too, so will make this course into the multimedia courseware,To improving expression and interaction of the teaching media, promoting the overall optimization of content of courses of the classroom, teaching method, teaching course, It is very essential and useful to improve the teaching result.
Among the thesis material, some content these make the multimedia teaching courseware chapter two content of " mobile communication " mainly, Including digital frequency modulate, digital phase place modulate, orthogonal amplitude modulate, expand frequency spectrum modulate with large signal carriers modulating these kinds of modulation technology with many signal carriers,Have introduced the basic principles of these kinds of modulation ways and implementation method in the courseware in detail.
Multimedia courseware as a modern multi-media education an important carrier, and its wealth of expression, good interaction and sharing great, and will certainly in our future life and learning to play a greater role; At the same time, in the next the information society, information society, as the support of technology, mobile communication technology will have greater development, so this course made multimedia courseware to improve the performance of the teaching media and interactivity, to promote classroom teaching content, teaching methods, teaching a comprehensive optimization process to improve the effectiveness of the teaching is very necessary and useful.
In this paper materials, mainly the "Mobile Communications" in Chapter II
