摘　　要：在多址通讯的情况下,常规的信道分配方法受到链路调度的制约,分配方法的运行效率并不高。基于此提出了基于ZIPF分布的多址通讯快速动态信道分配方法。首先,以多址通讯中数据项的访问频率和多个信道为输入,通过ZIPF分布处理平衡多址通讯数据项;其次,计算多址通讯对应链路的优先级消除其对信道分配的干扰;然后,预测多址通讯业务量设计对应的分配方案;最后,设计对比实验。实验结果表明:所提方法传输时延稳定、内存占比低,其运行效率稳定。In the case of multi-access communication,the conventional channel allocation method is constrained by link scheduling,and the operation efficiency of the allocation method is not high.A fast dynamic channel allocation method based on ZIPF distribution for multi-access communication is proposed.Firstly,ZIPF is used to process balanced multi-access communication data items with the access frequency of data items and multiple channels as input.Secondly,the priority of the multiple-access communication link is calculated to eliminate its interference to channel allocation.Then,the traffic allocation scheme of multi-access communication is designed.Finally,a comparative experiment is designed.The experimental results show that the proposed method has stable transmission delay,low memory ratio,stable operation efficiency.
