Abstract :
This paper studies the feasibility of applying TDD technique to a conventional FDD-CDMA system. This is achieved by creating a TDD-CDMA picocell underlaying the existing FDD-CDMA macrocellular network. The system performance is measured in terms of the outage probability. From the simulation results, we discover that spectrum sharing between TDD-CDMA and FDD-CDMA is feasible and that under our assumed interference scenario the performance of the TDD-/FDD-CDMA frequency sharing cellular network is bound by the FDD forward link frequency
