At the same time, the important parts of communication system are introduced in detail, including coding, spread spectrum, decoding, modulation and channel transmission, etc. This thesis also refers to the condition, advantages and development of CDMA system to show its potential and value for research. What’s more, the thesis also using an example to give a brief introduction of the simulation platform of MATLAB software, it is such a powerful, easy operating software that is widely used in many fields. This simulation platform displays the superiority of CDMA effectively, and the result shows that CDMA can receive the accurately data even in a big noise.【Key words】Code Division Multiple Access, communication system, MATLAB, simulation下载后可任意编辑目录第一章 绪论..................................
