Hello Ali:
You will have to 1. sync their clocks, and then 2. compensate their phase offsets. You will need to have some kind of a clock source (can be pretty expensive).
You will also have to modify gr-doa, so as it would take multiple USRPs as input sources.

Dear Kyeong,
Thank you very much for your response.
KrakenSDR looks interesting. Unfortunatly it isn't an option
now. Could you please provide me with more information/materials about the modifications required for using X310-SBX?
Kind regards,
Ali

Hello Ali:
B210 does have suitable frontends, but you will only get 2 channels (instead of 4), and you will have to make some modifications to the software.
Other boards are also usuable, but you will have to synchronize them (using something like an Octoclock) and compensate their phase offsets manually (by using something like a noise generator). And again, you may have to make some modifications to the gr-doa
software.
A cheaper (non-USRP) alternative to this is KrakenSDR ( https://www.crowdsupply.com/krakenrf/krakensdr ). You may want to stick with USRPs for academic purposes, though,
if you can afford (as KrakenSDR is still at its infancy).

Dear all,
I need to do the angle of arrival by using USRP (gr-doa) and I know that this example requires X310-TwinRX. Unfortunately, I only have X310-SBX, B210 and N210-CBX. Would be possible to use any of these USRPs instead?
Any help would be much appreciated.
Thank you very much in advance.
Kind regards,
Ali |
