M-aray Phase Shift Key Modulation

说明：  能够实现对故障数据进行分解，比EMD分解效果更好(It can decompose the fault data, which is better than EMD)

MCS51单片机软件实验，实验中包含了相关程序结果(MCS51 Microcontroller Software The experimental procedures included the results)

这是SSR算法与直方图均衡化相结合的matlab代码，可以增强模糊且较暗的图像。 (this is SSR algorithm and HE。。。)

coastguard_qcif.yuv，foreman_qcif.yuv，hall_qcif.yuv，soccer_qcif.yuv四个标准视频的测试文件，这是15hz版本，内含读取yuv文件的matlab源代码代码(the 15hz video files. (coastguard_qcif.yuv，foreman_qcif.yuv，hall_qcif.yuv，soccer_qcif.yuv))

说明：   本文在研究IEEE802.16e协议和SIP协议的基础上，提出了利用 SIP解决IEEE802.16接入网络中端到端切换的新方案。该方案采用跨 层切换的设计思想，联合MAC层和应用层SIP协议，在底层链路切换 的同时，完成应用层会话的修改，加快了切换过程，减少了切换时延， 提高了切换成功率。本文基于NS2仿真平台，完成了相应的仿真平台 搭建过程，实现了SIP协议模块和WiMAX协议模块的融合，扩展了SIP 协议模块的部分消息，最终在基于SIP协议模块和WiMAX协议的统一 NS2平台上实现了基于WiMAX接入、支持SIP扩展功能的SIP会话建 立和修改过程。 ( On the basis of study of WiMfAX and SIP, a new mechanism using SIP to achieve end-to-end handoff under IEEE802.16e access networks is Ob proposed handoffs, in this thesis. The mechanism adopts a cross-layer design which means that the l}iIAC layer handoff procedure can interleaved with that of the application layer. During the handoff at link )
