Re: [Discuss-gnuradio] Is USRP mandatory for gnu radio for cognitive radio

Thanks, I'll check it out.

Hello M S Sumi,

The GNU Radio tutorials are a great place to gain an understanding of doing digital signal processing without hardware connected and then the later tutorial covers the use of hardware to see actual RF signals.

Dear M S SUMI:

You don't need to have USRPs, but you probably want to have SDR transceiver board(s) with you if you want to deal with the real-world signals. Without SDR boards, you can only do simulations with synthetic data (which is often fine).

Look for RTL-SDR (receive only), ADALM-PLUTO, or LimeSDR Mini (not released yet) if you need cheaper alternatives to USRP.

I am learning to use gnu radio for cognitive radio spectrum sensing. Whether gnu radio software can be used for primary signal detection without interfacing a USRP kit...
