摘要
随着现代通信技术的快速发展,移动通信系统的研究和开发成为热点,并不断有着新的突破。该文在Matlab6.5/Simulink环境下成功地建立了IS-95标准N-CDMA移动通信系统反向业务信道的模型,解决了模型创建中串并转换、并串转换、数据帧格式转换等几个关键问题,在此基础上进行了系统模型仿真,获得标准的调制信号,并对信号的频谱及其通过高斯信道的误码率进行了研究分析,给出研究结果,为实际系统的设计提供了有效的依据。
<Abstrcat>With the rapid development of modern communication technology ,the research and exploitation of mobile communication system become hotspot, and continuously gets new breakthrough. This article discusses the model of the reverse traffic channel of N-CDMA which is successfully constructed under Matlab6.5/Simulink.It has settled some important problems in modeling, such as serial to parallel conversion, parallel to serial conversion, data frame format conversion and so on . It also simulates the system model and gets the modulated signals whose spectrum has been observed and error rates through AWGN have been researched. Results provide reference for practical system design.
