Abstract: This article is devoted to an interesting educational direction i.e. Radio Frequency (RF) concepts and the use of basic digital signal processing tools for the development of real-time applications. A system with digital audio broadcasting (DAB) based generalised frequency division multiplexing (GFDM) is considered, estimates of its transmission modes are utilized. Software Defined Radio (SDR) is an advanced radio which can tune to any recurrence band and goes about as handset by utilizing universal software radio peripheral device (USRP) Programmable with LabVIEW programming. In this paper GFDM system proposal for digital audio broadcasting is investigated. The kernel is GFDM system, Emphasis is on the use of channel coding with low-density parity-check and convolutional codes at the transceiver. Furthermore, by using LabVIEW RF communications module software, a transceiver platform is built-up to analyze the performance of the DAB channel based on USRP hardware set up. BER is calculated under rural area (RA) consideration for entire area with quality of audio signal received is mentioned with different colours along with goggle map. This experiment was successfully conducted in GITAM University, India. The paper concludes with better audio quality of GFDM and slightly outperforms OFDM in terms of BER by a margin of 13% in the RA only.
Keyword: BER, DAB, GFDM, SDR.
