Software Defined Radio or SDR is basically a radio functionality implemented in software. Going into the subtleties of an SDR, the authors can find that there is a hardware component to serve the purpose of an RF front end, without which a radio is non-functional. GNU-Radio Companion serves as the software end to which the hardware is attached. There have been advances in the hardware end over the years and this paper serves to compare the different hardware counterparts of the GNU-Radio companion. They have taken hardwares extending from the high cost series of Universal Software Radio Peripherals (USRPs) to medium cost FUN-Cube Dongle (FCD) to the extremely low cost RTL-SDR dongle.
