【摘要】 TDD-CDMA系统由于上下行业务量的不对称,因此会产生严重的小区间干扰,需要使用动态信道分配算法(DCA)来适应上下行业务量的动态不平衡。文中提出了一种基于平均功率值的DCA算法。它通过采用平均功率控制的算法对功率进行处理,以提高信道利用率;并避免基站间的相互干扰来改善系统性能,从而提高系统容量。仿真结果表明,提出的算法能够显著地改善系统指标,达到优化效果。更多还原

【Abstract】 For the asymmetry of uplink and downlink traffic in TDD-CDMA system, there would be serious interference between among the cells. The dynamic channel allocation algorithm would thus be adopted to reduce the interference. In this paper, a novel and advanced DCA algorithm based on the average power value is presented. The algorithm raises the channel utilization and system capacity. Simulation results show that this algorithm can obviously improve the system performance.更多还原
