| Abstract: | To counter the presence of a large amount of noise and interference in HFC upstream channel,this paper focus on a S-CDMA(Synchronous Code Division Multiple Access)based upstream transport scheme.We discuss the characteristics of S-CDMA,system's compose and key techniques in details.We also analyse some issue of the implementation. |
