Introduction
With the development of munications, the work technology is showing its great importance day by day.
随着现代通信的发展,接入网技术正显示出其重视。
The work technology can be divided into four categories:advanced cotton cable technology, FITL system,work and WLL system.
接入网技术可分为四类:先进的棉花电缆技术,光纤环路系统、有线电视网络和系统广泛分布有线电视网络。
The popularly distributed work,for its relatively low price and good broad band transport characteristics, may be the most prospective media to realize multi-munications including voice, data and moving picture.
因其相对较低的价格和良好的宽带运输特点,可能是最准媒体实现多业务通信包括语音,数据和移动图像。
In this paper,a new scheme using DS—CDMA to realize Bi-munications in work is addressed.
在本文使用码分多址的新方案在有线电视网络实现双向通信地址。
As a colusion,we can find that this is economical and with good pared with some other schemes.
作为一个解决方案,我们可以发现这是经济和与其他方案相比具有良好的性能。
work
The work is a hierarchical and single-direction
system,as we can see from , composed of three parts:
front end part,transportation part and user dis
