摘要
HFC网络回传噪声的"漏斗"效应及传输速率一直严重制约着广电网双向传输业务的发展,基于移动通信CDMA技术的S-CDMA则非常圆满地解决了这两个问题,对S-CDMA技术在广电网双向改造中的应用进行了简要论述。
The development of bidirectional transmission has been seriously restricted by Funnel Effect and the transmission rate of HFC network noise return. Based on CDMA technology, S - CDMA is a very satisfactory solution to the two issues above. In this paper, the applications of S - CDMA technology in the bidirectional transmission were analyzed in brief.
