Detailed performance analysis of digital audio broadcasting under different modulation schemes and channels

Abstract

In this paper analysis of Digital audio broadcasting on its four different modes have been performed. All the possible four modes have been executed and simulated on SIMULINK platform under different types of modulation schemes and channels. This paper is trying to develop a novel scheme of low cost, complexity wise reduced communication model for open air performance analysis. Thus the paper implements a novel method for the purpose of quality improvement in the communication equipment improvement using DAB. The results that have been performed on different types of channels are additive white Gaussian noise, Rayleigh and Rician fading channels. Similarly different modulation schemes in the model for example BPSK, QPSK, 16 QAM on different channels has been done. Of all the different types of channels in MATLAB & SIMULINK software for which a complete detailed table analysis has been done has found that of all the possible four modes the fourth mode has outperformed with good level of BER performance ranging between 20% to 22%. This paper has shown that with QPSK and AWGN Rayleigh channel mode 4 has proved to be the best working mode.
