closed-loop-sim-with-LQR

labveiw实现基带信号的幅度调制（AM），频率调制(FM)和相位调制(PM)，可以在波形图中看到调制信号和调制后信号的叠加和对比，可以看到频域波形。载波与基带幅度和频率参数均可改变。(Baseband AM/FM/PM in labview. In the vi, you ll be able to see the modulated signal in both time and frequency domain.)

cvi入门小程序，流水灯、定时器、示波器、串口、数据库等(Cvi entry small program, water lights, timers, oscilloscopes, serial, and so on)

labview对制图软件生成的dxf文件内容进行更改和读取(labview for the mapping software generated dxf file content changes and reading)

Labview基于声卡的频谱分析 声卡采集声音数据,显示其波形,通过滤波器和加窗处理进行功率谱分析(Labview based sound card spectrum analysis Sound card data collection, display its waveform, through the filter and window processing power spectrum analysis)

labview 下的串口编写思路程序，含有多线程，中断，串口参数的保存和例子等。(Labview serial port under the writing way of thinking, the program contains a multi-threaded, interruption, save and example of serial port parameters, etc.)

可用于Labview中csv 文件数据处理，读取文件中所有数据(csv file to read VI)

实现了Labview中格式为TDMS的数据文件的读取，并能够在波形图表中显示数据文件中记录的波形。(Achieved in Labview TDMS data file format is read, and the ability to display data in the waveform chart waveform records in the file.)

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.)

说明：  labview宝典书籍的全部代码，希望有助于同学们的学习，所有代码都可以运行(Labview books all the code, I hope to help students learn, all the code can run)

说明：  调用dll文件截取最前端窗口的图像，调用需要等待200ms(Calling DLL file to intercept the front-end image)
