PI_Feedforward inverse control

说明：  简单的用户登录系统，用户管理功能。上位机程序开发系统，用户登录管理系统(Simple user login system, user management function.PC program development system, user login management system)

第一部分产生最大128位随机数 第二部分用汉明距离检测误码率 第三部分，第一和第二再加调制（BPSK+QPSK）加白高斯噪声通道awgn，得到结果并用图形显示。(part1: source.vi generate a ramdom bit sequence. part2: erro detection get BER via Humming Dacetance. Part3: part 1+ 2, and modelation (BPSK or QPSK), and AWGN,get BER and show it in diagram.)

实现：生产者消费者循环，labview与生物学结合，(Implementation: producer consumer loop, labview combined with biology,)

labview程序，可以接收和发送modbus rtu协议信息。“CRC VHL”为循环冗余校验(Labview program)

基于labview的双通道数据采集处理系统，双界面，含置滤波器（巴特沃斯，切比雪夫可选），含加窗数据处理，支持数据记录并回放，用了信号源仿真，只需把信号源换成输入即可(Labview-based dual-channel data acquisition and processing system, dual interface, including home filters (Butterworth, Chebyshev optional), containing windowed data processing, data recording and playback support, with a source simulation, simply put input signal source can be replaced)

?运用数字信号处理及相关专业知识设计一个基于LabVIEW的虚拟仪器，采集一个信号，对其进行FIR滤波，将滤波后的波形输出并分析结果(Using digital signal processing and related professional knowledge to design a virtual instrument based on LabVIEW, collect a signal, carry out FIR filtering, output the filtered waveform and analyze the result.)

Labview的3D控件的功能介绍，还有三个例子程序：陀螺仪，2D魔方，3D魔方。(Function Labview 3D controls introduction, there are three examples: gyroscope, 2D Rubik' s Cube, 3D cube.)

说明：  使用Labview创建TCP通信端口，实现两个终端之间的通信(Create TCP communication port to realize communication between two terminals based Labview)

可以在曲线图上画任意曲线并对曲线做修改。(Can make changes and draw any curve on a graph curve.)

LABVIEW数据库连接，可以作为一个模板进行使用(LABVIEW database connection)
