说明：  本文正是在研究WIMAX/802.16e协议和FMIPv6协议的基础之 上，提出了基于FMIPv6的WIMAX网络快速切换机制，该方案采用跨 层切换的思想，MAC层联合网络层同时进行切换，在链路尚未断开 之前即完成新转交地址(NCOA)获取等功能，从而加快了切换进程， 减小了切换时延和切换时的丢包率。在提出本切换机制的基础上，本 文在NSZ仿真平台上对所提出的切换方案做了系统性的性能仿真，通 过仿真结果验证了方案的可行性和优越性。 ( In this paper, IEEE802.16e standard is described at first. Then an introduction for the basic knowledge and research in MIPv6 and FMIPv6 protocol is given. A fast handover scheme of WiMAX network which based on FMIPv6 protocol is suggested, which implements the fast handover at IP layer associating with MAC layer at the same time. scheme minimizes handover latency by predicting and preparing This the impending handover in advance. Finally, simulation are carried out to evaluate the performance of this fast handover scheme. The result of the simulation shows that the fast handover scheme has good performance. )

说明：  Matlab使用矩量法求解同轴方腔滤波器腔间耦合系数 求解两个同轴方腔在一定的开窗大小下，确定耦合系数。 首先利用矩量法求解两个同轴方腔的互电容和自电容，详细原理见参考书。 其次再由耦合系数得到两个腔体间耦合窗的大小，这在工程实践中具有很大的作用，耦合系数K的求解详见m文件。(Matlab using the method of moments coaxial cavity filter cavity coupling coefficient between the two coaxial cavity for solving a certain window size, determine the coupling coefficient. First use of moment method to solve two coaxial cavity of the mutual capacitance and self-capacitance, see the detailed principles of reference. Secondly, the coupling coefficients are then the coupling between the two cavities the size of the window, which in engineering practice has a significant role, see the solution coupling coefficient K m file.)
