【摘要】 从降低开销的角度出发,提出了自适应的CDMA(Code Division Multiple Access)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。通过系统级仿真从功率控制的方面防止了拥塞的发生。更多还原

【Abstract】 An adaptive congestion control algorithm in CDMA(Code Division Multiple Access) systems from the aspect of reducing cost is proposed In this scheme data rates in probabilistic manner according to a RAB (reverse activity bit) 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.Through system-level simulation from the power control of the area to prevent the occurrence of congestion更多还原
