| 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.

| Abstract: | 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. |
