这是一个QPSK的调制及解调过程的例子，供大家学习参考(This is the example of a QPSK modulation and demodulation process for them to learn from the reference)

信号发生器，带扫频，带频率的切换！最小可以0.1HZ。(Frequency sweep signal generator, belt, belt frequency switch! Minimum to 0.1 HZ.)

倍频程带通滤波器,实现倍频程分析和计算信号的有效值(Octave bandpass filter to achieve octave analysis and calculate the effective value of the signal)

说明：  使用usrp n210,利用Labview实现正弦信号收发，一方面可以利用labview实现实际信号在空中收发，另一方面可以检验设备正常运行。(Using USRP N210 and Labview to transmit and receive sinusoidal signals, on the one hand, it can use LabVIEW to transmit and receive actual signals in the air, on the other hand, it can check the normal operation of the equipment.)

labview与西门子plc通讯工具，读取plc内的数据，修改plc内部寄存器值，PLC交互(LabVIEW and Siemens PLC communication tools, read the PLC data, modify the PLC internal register value, PLC interaction)

LABVIEW信息处理，可以实时监测振动信号波形的例样程序(LABVIEW information processing, real-time monitoring program examples like the vibration signal waveform)

USB-6008说明与使用注意事项lab运用与说明(6008 Description and Use Precautions)

labview调用dll实现QR二维码生成，包含dll说明等，可作为子vi直接使用(LabVIEW calls the DLL implementation of QR code generation, including DLL, can be directly used as a sub VI )

气体体积检测模块，用于气体实时监测，可实现气体体积测量，手持机中的一部分，可与本人另外WINCE模块连用,亦可以单独使用(LABVIEW )

本文在LabVIEW和NI-IMAQ Vision软件平台下，利用通用图像采集卡开发一种图像实时采集处理虚拟仪器系统。通过调用动态链接库驱动通用图像采集卡完成图像采集，采集图像的帧速率达到25帧每秒。利用NI-IMAQ Vision视频处理模块，进行图像处理，以完成光电探测器的标定。该系统具有灵活性强、可靠性高、性价比高等优点。(In LabVIEW and NI-IMAQ Vision software platform, the use of a common frame grabber to develop a real time image acquisition and processing the virtual instrument system. Drive general-purpose image acquisition card by calling the dynamic link library complete image acquisition, the acquisition of the image frame rate up to 25 per second. NI-IMAQ Vision video processing module, image processing, in order to complete the calibration of the photodetector. The system has the flexibility, high reliability, high cost.)
