摘　　要：通过分析时分双工-码分多址(TDD-CDMA)系统中业务接入容量与干扰之间的关系以及TDD-CDMA干扰分布的特殊性,使用Delbrouck算法,对TDD-CDMA上行系统进行了多业务接入容量研究,可以求得多维损失制系统的呼叫阻塞率、流量阻塞率、时间阻塞率及承载流量.最后给出了数值和仿真分析结果,证明了该方法的有效性.An approach for calculating the multi-services access capacities of uplink time division duplexing-coding division multiple access （TDD-CDMA） system is proposed. The relationship between service access capacities and TDD-CDMA interference is analyzed. And the specialty of TDD-CDMA interference distribution is also considered. By using Delbrouck＇s algorithm, the call congestion, traffic congestion, time congestion and carried traffic of different services in a multi-dimensional loss TDD- CDMA system can be resolved. Both analysis and simulation results are given to support the method mentioned above.
