Hi Marcus!
I am implementing a transmitter and a receiver model using
two USRP N210s. Both are using GFSK modulation, and the data
is transmitted at 2.4 GHz.
Cool :)
I would like to add a phase shift at the transmitter side
via the use of a multiplier block with an exponential.
Ah, so a multiply_const with a constant of
$e^{j\frac{2\pi}{f_\text{sample}\varphi}$, yeah.
Then, at the receiver I would like to receive this
transmitted signal and check if the phase matches the one that
was transmitted. This is why I need a measuring method.
Well, you can't see absolute phase without further ado – that would
need your TX and RX to be phase-synchronized (you don't know the
electrical length between your transmitter and receiver, it's
absolutely random by itself).
Best regards,
Marcus
