| Abstract: | 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. |
