| Normaly mobile telecommunication systems always be restrict by power and bandwidth, And CDMA system is a interference-limited system,.As keep the communications quality the same time high speed DATA transmition service and Large system capacity are needed.These request even maybe restrict in technology ,so these request need more complex radio technology and error control technology ,also has high level signaling modulation method.In mobile telecommunication system RF environment are very complex and multiplex,so many different wirelss systems in same space ,if use old modulation technology can not solution those problem . But with the morden computer technology development ,CAD/CAM technology has been used widely ,espacily the software toolkit with special telecommunication simulation development fuctional . Simulation use computer software not only can save reduce the network design cost and develop efficience ,but also simulation can help the designer and opreator's enginner understanding the radio technology easier. As a success simulation software provide the user a vitual environment like use equipment in laboratory ,can easily measurement the system you want to analysis,and easily change the parameters to reaserch .Because you can change the Filters bandwith and SNR etc,and you can direct-viewing how the system works when those change happened . This document's chapter1 introduct the main procedure of telecommunication simulation , and why the important of the simulation.In this chapter also introduction the software MALTLAB .The... |
