Adding white noise #344

Closed fener1efes2 closed 2 years ago

fener1efes2 commented 2 years ago

I transmit the signals created by GPS-SDR-SIM by using HackRF. I connected U-BLOX GPS L1 C/A receiver with cable to HackRF. Naturally, C/No values of the GPS signal becomes so high like 55dB/Hz. Is there a way that I can add white noise at the output of the HackRF while transmitting GPS signal created by GPS-SDR-SIM?

Use attenuators.
