摘　　要：TD-SCDMA是第三代移动通信系统三大国际主流标准之一。该系统利用动态信道分配技术,可以充分发挥TD-SCDMA系统资源分配灵活高效的特点,从而能在对称和非对称的3G业务中获得最佳的频谱效率。介绍了TD-SCDMA系统中的动态信道分配(DCA)技术,详细论述了信道优先级排队、信道选择、信道调整、资源整合等DCA技术的主要处理过程,并分析了DCA算法的系统性能。TD-SCDMA as one of the three international mainstream standards of the third-generation mobile communication system employs DCA technology and can make full use of its characteristic of high flexibility and efficiency for resource allocation thus can get the best spectrum efficiency in symmetric and asymmetric services of 3G. This paper discussed the DCA technology applied in TD-SCDMA as well as the key working process such as channel priority queuing channel selection channel adjustment and resource integration. The system performance of DCA was also provided.
