Abstract :
This paper considers a time division duplex (TDD) extension applied to a conventional frequency division duplex (FDD) CDMA cellular system. The FDD-CDMA cellular system is overlaid by small TDD-CDMA cells which can cover capacity “hot-spots” such as in offices and public buildings. The TDD-CDMA base stations have lower complexity than the FDD-CDMA base stations and are able to support asymmetric traffic at high bit rates
