| 摘 要： | 从降低开销的角度出发，提出了一种自适应的码分多址（CDMA）系统拥塞控制算法。在该算法中，数据移动台根据基站广播的反向激活比特和自适应概率值以概率方式升降速率，其中自适应概率值根据系统剩余容量动态地调整。经过理论分析和系统级仿真，验证了自适应拥塞控制算法在控制系统负载的条件下，提高了系统吞吐量。

| Abstract: | An adaptive congestion control algorithm in code division multiple access(CDMA) systems from the aspect of reducing cost is proposed.In this scheme,data rates in probabilistic manner accor-(ding) to a reverse activity bit(RAB) and an adaptive probability value broadcasted by the base station are increased or reduced in data mobiles,whereas the adaptive probability value is dynamically adjusted on the basis of the residual capacity of system.It is proved by analysis in theory and system level simulation that the adaptive congestion control algorithm can enlarge system throughput while controlling system load. |
