The National Instruments PCI-4472 and PXI-4472 are 8-channel dynamic signal acquisition devices for making high-accuracy audio-frequency measurements. The PCI-4474 is a similar 4-channel board. The vibration-optimized NI PXI-4472B offers a

使用astar算法（A星算法）进行路径规划，可实时进行障碍物添加，进行路径修改。-Use astar algorithm (A star algorithm) for path planning, real-time obstacle can add, modify the path.

基于Labview的A*寻路算法，代码简单易懂(Labview based A* pathfinding algorithm, the code simple and easy to understand)

通过labview 编写在usrp上的关于QAM信号在发送端调制，接收端解调，可以观察信号的星状图，眼图。(The QAM signal on the USRP is modulated at the transmitter and demodulated at the receiver by labview. The star and eye diagrams of the signal can be observed.)
