| 摘 要： | 提出了一种在码分多址（CDMA）系统中基于多小区功率增长估计的下行接纳控制（AC）算法。在新呼叫到达时，不仅考虑接纳新用户后接入小区基站发射功率的增长，同时考虑接入后相邻小区基站发射功率的增长，给出了相邻小区基站发射功率增长估计的方法。仿真结果表明在小区间业务负荷不均匀的情况下，采用基于多小区功率增长估计的接纳控制算法能有效地降低错误接纳概率，提高系统吞吐量。

| Abstract: | A downlink admission control(AC) algorithm is proposed in code division multiple access(CDMA)systems,that is based on multi-cell transmitted power raised estimation.The transmitted power raised in the adjacent base stations is taken into account as well as in the serving one when a new call is arrived. A method is derived to estimate the transmitted power in the adjacent base stations.Simulation results show that under non-homogeneous conditions,the proposed algorithm reduces the probability of wrong admission,accordingly the throughput is increased. |
