I would like to do the spectrum sensing for the whole 2.4G ISM band ( 2.4 -2.4835GHz ) to figure out where the spectrum holes are. I would like to know if it is possible to sense the whole band,2.4-2.4835GHz, through the USRP? However, the ADC can only support 64Msamples/sec. How can I scan the whole ISM band and draw the spectrogram of the ISM band,2.4-2.4835GHz, through the USRP? Any hints? Thank you so much for your time.
