We previously proposed a next generation cellular system for IMT-2000based on wideband DS-CDMA with TDD scheme and have evaluated its performance by computer simulation, laboratory and field experiments. This paper presents the design concept of TDD-mode operation on wideband DS-CDMA systems. These systems employ almost the same techniques with a little difference as FDD-mode. We also present the schemes ofthe TDD-mode specific techniques suchas fast cell search, transmission diversity and transmitter power control and show the evaluation results of themare effective. Performance can be improved by use of enhanced techniques such as interference cancellation and adaptive antenna array diversity.
