本文针对扩频技术在WCDMA系统的中的应用进行简单论述及仿真。文中先对扩频通信基本原理及WCDMA的基本原理进行了简单的介绍，也对移动通信和扩频通信的发展进行了简要说明。再对扩频通信技术在WCDMA中的应用进行了简单介绍，最后重点对WCDMA中的扩频、加扰、调制以及解扩、解扰、解调,进行了仿真模型的建立和对仿真结果进行了时域分析。

-Conclusion In this paper the application of spread spectrum technology in WCDMA system will be briefly discussed and simulation. This paper first the basic principles and the basic principles of spread spectrum communication WCDMA is a brief introduction on the development of mobile communications and spread spectrum communication are briefly described. And then the spread spectrum communication technology in WCDMA in a brief introduction, finally focusing on the WCDMA spreading, scrambling, modulation and despreading, descrambling, demodulation, carried out to establish the simulation model and the simulation results the time-domain analysis.
