为学生预约、排队上机实习所作的程序 需要实现功能： 1，查询，根据输入时间，输出机位信息。 2，即为预定，根据输入的日期和时间段查询是否有空机位，若有则预约，若无则提供最近空机时间段。另：若用户要求在非空时间上机，则将用户信息插入该时间段的等待列表. 3,退出预定，根据输入的时间，撤销该时间的预定。 4，查询是否有等待的信息，若有则按顺序显示联系方式，若无则显示提示信息。(Program for student appointment and queuing Functions need to be implemented: 1, query, according to the input time, output the information of the machine. 2, is a reservation, according to the input date and time to query whether there is an empty space, if there is an appointment, if there is no time to provide the nearest flight time. Also: if the user requests the machine on non empty time, the user information is inserted into the waiting list of the time period. 3, withdrawing from the reservation and revoking the scheduled time according to the time of the input. 4, query whether there is waiting information, if there is the order to display the contact in order, if there is no display of prompt information.)

说明：  吴镇扬老师的数字信号处理教材，内容简介明了，是东大考研的必备材料。也是技术人员学习的重要参考资料。(Zhen-Yang Wu teacher' s digital signal processing textbook, Introduction to understand, is the essential material of Tokyo Entrance Examination. Technical staff is also an important reference for learning.)

说明：  宽带无线通信仿真，有关于瑞丽信道建模，导频信道估计，理想信道估计，最大比合并与等增益合并，直接序列扩频(matlab,simulink,STBC,VBLAST)

EMD改进版CEEMDAN，具体详见百度(CEEMDAN algorithm further reduces the modal effect by adding adaptive noise and has better convergence good)

e-kernel操作系统内核，支持TI omap5910处理机。(e-kernel operating system kernel to support TI omap5910 processor.)

超好用的vb表格小控件， 实现随心所欲的编辑，你值得拥有！(Super use of VB form small controls, you deserve to have!)

说明：  用matlab编程模拟实现大尺度衰落模型(Large scale fading model)

基于psim的SVPWM仿真，利用C-BLOCK模块搭建。(The SVPWM simulation based on PSIM is built with the C-BLOCK module.)

实现梯形图编辑器的帮助文档，具有很高的参考价值。(This doc is very good for your plc ladder editor.please download it.)
