Hi Fernando!

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
