Can Matlab calibrate USRP N310 SDR? + Filtering noise

Hello, I am new to Mathlab and wanted to know if any addons can assist me in phase sync the 4 array antennas of my N310 sdr. I see addons that help with UHD drivers and such, but nothing in this regard. If not, any suggestions?

Also, do people use mathlab mostly for signal collection and noise filtering? I might be doing things the hard way and need to understand how the pros do things! Thanks

Hi J,

Please have a look at this example - https://www.mathworks.com/help/comm/usrpradio/ug/direction-of-arrival-estimation-using-music-and-twinrx.html.

In this example, a phase calibration process is carried out to estimate and correct for phase offset the four channels on a USRP X310 with TwinRX daughterboards. Although the example has not been written for an N310, it should be applicable.

People do all sorts with MATLAB and USRPs. Please have a look at Wireless Testbench which is the toolbox which supports USRP N3xx, X3xx and X4xx. The primary workflows are signal transmit and capture, signal detection, spectrum monitoring, code generation and deployment. There is a substantial list of examples - https://www.mathworks.com/help/wireless-testbench/examples.html?s_tid=CRUX_topnav.

If you have a USRP2, B2xx or N2xx, you should look at the Communications Toolbox Support Package for USRP Radio.

Thanks,

Neil

This might have come from a gnu radio project I found earlier. Regardless, I am glad Mathlab is supporting this, thank you! https://www.mathworks.com/help/comm/usrpradio/ug/direction-of-arrival-estimation-using-music-and-twinrx.html
