Experimental study on wide band FM receiver using GNURadio and RTL-SDR

This paper focuses on the open source GNURadio Software and studies its use as a research tool coupled with USRP and RTL SDR. USRP, RTL SDR and GNU Radio software suite is introduced and briefly discussed. GNU Radio software suite can act as a simulation tool or a software subsystem to drive a SDR transceiver hardware. This is shown by implementing WBFM receiver using RTL SDR with GNU Radio. It concludes by comparing the cheap yet effective RTL SDR with the costly but accurate USRP hardware.
