| 摘 要： | 讨论了基于载干比测量的动态信道分配方案。从理论上分析了干扰自适应的动态信道分配（ＩＡ－ＤＣＡ）的特点，并给出了它所能达到的极限系统容量。通过对固定信道分配（ＦＣＡ），话务量自适应动态信道分配（ＴＡ－ＤＣＡ）和ＩＡ－ＤＣＡ的仿真，比较了各信道分配方案的含量，理论分析和仿真实验均说明，基于载干比测量的动态信道分配方案具有明显的容量优势，而且容量的改善和系统中所有连接的平均载干比测量的动态信道分配方案具

| Abstract: | The interference adaptive dynamic channel assignment (IA DCA) based on carrier interference ratio (CIR) measurement is studied. The characteristics of IA DCA are investigated and the maximum system capacity of the scheme is derived. By simulations, the typical channel assignment schemes, fixed channel assignment (FCA), traffic adaptive dynamic channel assignment (TA DCA) and IA DCA, are compared and the results validate the analytical approach. Both the analysis and simulation show that the IA DCA can increase the capacity of cellular system, while the capacity increase is correlative with system CIR redundancy. |
