I’m working on synchronising two USRPs (connected via a MIMO) and have
calibrated the time-offset which occurs between them for a given set of
signal generator’s frequency, USRPs frequency and the sampling rate.
My next step is to do a phase-compensation for one of the USRPs so that
both are aligned in the time-domain. I read from
that for Phase-shifting, we need to use MRC algorithm or Periodic
Calibration. Also I saw that a “Phase Shift” block has been used in that
document which I guess was developed by the author who wrote it, as I
not find it in the GRC.
I’m willing to develop one such simple phase-shift block. Can anyone
suggest me how to approach in implementing it i.e in terms of any
algorithm’s reference that you can suggest to achieve this purpose?
Note: I want my Phase-Shift block to work in real time i.e it should be
able to adjust the phase-offset of one of the signals so that that
gets aligned with the other in the time-domain.
Thanks and Regards,
