Abstract

This paper analyzes the transmission of Audio File using NBFM modulation technique on the GNU Radio software platform. The NBFM modulation techniques are used broadly in audio communication and data transfer. The key concept around Software Defined Radio (SDR) is also described. Nowadays SDR has the attributes of remodel the system parameters without actually changing the hardware part. The employment is done on the GNU Radio Companion. In case of spectrum efficiency Narrowband FM (NBFM) is used but when better signal quality is considered Wideband FM (WBFM) is used for greater spectrum usage. The Audio signal reception and transmission is achieved by USRP (Universal software radio peripheral) and designed by GNU Radio 3. 7. 5. 1 in the laboratory ambiance.
