Y.S. Rao, A. Kripalani · 2003
This article presents key design characteristics of the cdma2000 RTT in terms of the proposed forward and reverse link structure. cdma2000 demonstrates that it can fully support IMT-2000 requirements and additional future services while providing backward compatibility to existing TIA/EIA-95-A/B cdmaOne networks. Major differences between the cdma2000 and WCDMA RTT proposals, in the areas of chip rate selection, pilot structure, base station synchronization, and frame length are highlighted in this article. Based on theoretical analyses, computer simulation results, and several years of experience with CDMA networks, it is concluded that cdma2000 provides several competitive and economical advantages to operators and end users.
