摘要
提供了一种对WCDMA系统单小区的PS业务的极限容量进行理论分析的方法。这种理论极限容量以最大用户数和系统极限吞吐量的形式给出。当然其他与容量相关的系统关键指标同时也给出了。通过对PS384/384业务的具体分析,我们发现系统地极限容量在基站附近可以到达2．4Mbits {7用户),在远点能达到1．7Mbits(5用户)。通过UT斯达康在信产部MTNET测试结果来看,由于无线信道的复杂性,以及可能的其他系统干扰,实际结果略小于理论结果。
In this paper, we provide an academic method to estimate the WCDMA system capacity pole for packet-switch traffic in a single cell, The capacity pole is presented in the form of throughput and max user number under some scenarios, Also other system key performance indications are attached too. From the numerical result we can see that for the PS384/384 traffic, theoretically, the system throughput can reach 2.4Mbits （7 user） near the Node B and 1.7Mbits （5 user） at the point that is far way the Node B. Through the MTNET test report of UTstarcom in Beijing, we can find that the real capacity is little less than the theoretical capacity pole due to the interference from other system and the complexity of the wireless channel.
