摘要

本文研究了将TDD技术应用于传统FDD-CDMA系统的可行性。这是通过在现有的FDD-CDMA大蜂窝网络基础上创建TDD-CDMA小蜂窝来实现的。系统性能是根据中断概率来衡量的。仿真结果表明，TDD- cdma和FDD- cdma之间的频谱共享是可行的，并且在我们假设的干扰场景下，TDD-/FDD- cdma共频蜂窝网络的性能受FDD前向链路频率的约束。

Feasibility study of TDD- and FDD-CDMA frequency sharing cellular networks

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.
