AN ANALYSIS OF THE TDMA AND S-CDMA TECHNOLOGIES OF DOCSIS 2.0

摘要

This paper analyzes the performance of TDMA and S-CDMA, which are the two modula-tion and multiple access techniques included in the newly developed DOCSIS 2.0 specifications. The two techniques are analyzed in the presence of linear signal distortion, ingress noise, and burst noise, which characterize cable plants. We also discuss how the transmission parameters can be adopted in both multiple access techniques to plant conditions in order to increase capacity or robustness. The results give a good summary of the relative merits of TDMA and S-CDMA.
