摘要
首先介绍了CDMA传输系统原理,然后以N-CDMA传输系统为例,重点阐述了CD-MA系统的前、反向传输系统中的信道结构、调制方式及其CDMA系统中所采用的关键技术。最后对CDMA系统的发展进行了简单的讨论和展望。
In this paper,CDMA transfer communicate system′s principle is introduced firstly.Then taking N-CDMA transfer system as an example,the paper lays emphasis on the channel structure and modulation of the front-reverse transfer systems. This paper also addresses the key technologies about CDMA system .The author briefly discusses the further development of CDMA system in the last.
