I am trying to create a random signal in GNU Radio (using DVB-S2 specs for the physical layer) and transmit this signal using a USRP X310. This is shown below:
Problem: I would like to be able to control the Es/No of this signal, as well as the symbol rate, but I don't know how. I'm brand new to DSP, so any help is appreciated!
Edit (2/9/2022): Removed throttle block, since it is unnecessary. To clarify, I would like to run GNU Radio on a USRP, then pipe the signal directly into another USRP to receive the signal. I would like to be able to control the Es/No in GNU Radio on the transmitter side, to test the capabilities of the receiver.
