Hi all,
I am working on the implementation of dynamic spectrum access with gnuradio and usrp2. I modified usrp_spectrum_sense for usrp2 to do the sensing job. However, I find the sensing speed is intolerably slow, which is about 1s for 1MHz.
I try to reduce the fft size but no significant improvement. My goal is to sense 4MHz in 10ms or so. I am wondering any ideas to improve the speed? Or is there any other ways to sense faster?
Any help would be appreciated! Thank you.
