I used the System Kernel-based clock and the time clock in LabVIEW NXG to check the loop execution time, but it is not completely precise.
I know that this is because the NI-USRP29XX product is not a calibration device, but I still want to measure time more than the conventional method.
Additionally, it takes a lot of development time to set up a wireless communication environment using only NI-USRP.
If you like me to conduct software defined radio-based experiments and research, we recommend that you use hardware such as DAQ.
Problems encountered
1. Inaccurate signal processing (only estimates are used)
2. You must implement functions such as Signal Detection yourself.
3. It is very different from the experimental environment written in various papers. (No DAQ, PXI)
Nevertheless, it cannot be denied that the NI-USRP is an excellent testbed and wireless communication device 😆
