求小波包的信息熵,每一步骤带相应的文字说明(wavelet)

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. )

The modeling and attitude stabilization control problems of a four-rotor vertical takeoff and landing unmanned air vehicle (UAV) known as the quadrotor are investigated.The quadrotor’s attitude is represented by the unit quaternion rather than Euler angles to avoid singularity problem. Taking dynamical behavior of motors into consideration and ignoring aerodynamic effect, a nonlinear controller is developed to stabilize the attitude.The control design is accomplished by using backstepping control technique.The proposed control law is based on the compensation for the Coriolis and gyroscope torques. Applying Lyapunov stability analysis proves that the closed-loop attitude system is asymptotic stable. Moreover, the controller can guarantee that all the states of the system are uniformly ultimately bounded in the presence of external disturbance torque.The effectiveness of the proposed control approach is analytically authenticated and also validated via simulation study.
