Traffic performance of CDMA/TDD-based wireless multimedia communications system

摘要

Recently, CDMA/TDD scheme has drawn considerable attention as means to realize efficient wireless multimedia communication system. In this paper, we propose time slot allocation algorithms for CDMA/TDD system to efficiently accommodate multimedia traffic, and evaluate the traffic performance by computer simulation. We compare the traffic performance of the CDMA/TDD system with that of CDMA/FDD and TDMA/TDD systems, and show that the CDMA/TDD system with the proposed algorithm can achieve the best performance among these systems.
