摘要 动态信道分配是TD-SCDMA的关键技术之一,根据网络负载和干扰的变化自适应地调整信道资源,使之达到合理配置。文中针对TD-SCDMA系统的帧结构,分析了双小区模型,并提出了一种采用双小区相同上下行时隙进行信道分配的方法,仿真结果表明:与传统的固定信道分配算法相比,推荐的算法大大提高了频谱利用率及系统容量。 Dynamical Channel Allocation (DCA) is one of the key technologies for TD-SCDMA systems. DCA plays an important role in assigning wireless resources properly,increasing system capacity in accordance with asymmetry data service in uplink and downlink to adapt to the payload and interference of the network. A Slow DCA Algorithm for TD-SCDMA system is proposed in this paper,a double-cell model is analyzed according to characteristics of the wireless frame in TD-SCDMA systems. Simulations results show that DCA outperforms the traditional fixed channel allocation (FCA) on frequency utilization and capacity.
