Hi all,
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 this
document 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
could 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 signal
gets aligned with the other in the time-domain.
Thanks and Regards,
