Hi Pablo, short answer: Because radio is hard, you need to do corrections before you actually have your signal where you want it, e.g. at 0Hz. long answer: The USRPs have mixers, yes. But you can't tell such a device just to tune to that e.g. GSM channel; this will not work due to frequency

[Discuss-gnuradio] BPSK demodulation

Hello, If UHD source acts as a mixer, why some examples (like usrp_rx_hrpt) use baseband information as the input of a PLL? Thank you in advance ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org
