+==== Signal Transmission and Processing with USRP2 and wiserd ====
+In this experiment we modify the [[http://www.orbit-lab.org/wiki/Tutorials/k0SDR/Tutorial05#SpectrumsensingwithUSRP2andwiserdOEDLandOML|Spectrum sensing with USRP2 and wiserd (OEDL and OML)]] tutorial.

+We increase the sampling rate to 10 MHz, so we can accurately receive frequencies up to 5 MHz greater or lesser than the receiver's carrier frequency. We then randomly select frequencies from 796 to 804 MHz to transmit for one second each. 
+[[BR]][[BR]]
+Using OML, we save the receiver readings to a file for processing in MATLAB/Octave. Using a MATLAB script, we generate a waterfall plot of the data, along with an animated power vs. frequency plot.
