Re: Phase Synchronize 2 USRP N200 w/ SBX cards

I repeated the experiments once again today and I got once again the same results. I still keep on randomly getting these 4 cases I attached on a previous message. I observed that cases 1.png and 3.png have a phase difference of +/- 180 degrees and cases 2.png and 4.png also have a phase dif

I have a query in to Ettus R&D about possible causes. But you might need, for now to do an initial phase Calibration when you start up. Sent from my iPhone > On Jun 11, 2021, at 3:39 AM, Skyvalakis Konstantinos > wrote: > >  > I repeated the experiments once again today and I got once aga

Hi, so I have been wondering what people do to implement mac layer type things with GNURadio? (for example automatic detection/handshaking type protocols before transmitting digital data packets.) >From my perspective gnuradio is good for physical layer development, but less so for state machine t

Hi Nick, You can take a look at the https://gitlab.com/marmote/gr-marmote3 repo as well. That has a custom waveform and custom MAC but it is a full fledged solution. The bare essentials (real time part) are kept in gnuradio, the rest is controlled from python using protocol buffers. Low latency bu
