摘要
介绍了第三代移动通信系统WCDMA扩频调制的原理及操作过程,利用MATLAB工具建立了WCDMA的上行链路扩频调制过程的仿真模型,最后给出了各个处理阶段信号的频谱图等仿真结果,并进行了分析,得出利用OVSF扩频码进行扩频调制能够很好地解决不同业务传送及多用户干扰的问题。
This paper illustrated the theory and operational process of WCDMA uplink channel＇ s spead spectrum and modulation. The simulation module of WCDMA uplink channel was founded by MATLAB, then the result of the simulation was given. Based on the preceding study and simulation it was concluded that the OVSF used in WCDMA could primely solve the problems of different operation＇s transmission and multi users＇ disturbance.
