摘　　要：以频率资源的可用状态为基础,探讨了一种新的动态频率管理方法.为了清晰描述频率资源状态,设计了频率指配表和可用频率表,分别表征频率受内外部环境的影响,还设计了根据变化的用频需求和无线信道状态对频率进行动态配置的机制.仿真结果表明,采用动态频率管理有效消解了系统内频率互扰,提高了频率资源利用率.Based on the useable state of spectrum resource, a new dynamic frequen- cy management method is discussed. For describing the states of spectrum resource clearly, frequency assignment list and useable frequency list were designed, which represent the influence upon frequency resource from inner and exterior system re-spectively. A dynamic frequency assignment mechanism with the variety of de-mands and channel states is designed. Simulation results show that interference in the system is eliminated effectively by dynamic frequency management, and spec-trum efficiency is improved.
