Abstract :
The broadcasting radio stations in several countries has benefitted by the usage of Digital Audio Broadcasting (DAB) technology, which replaces the usage of AM and FM broadcast services. An improved version of the Digital Audio Broadcasting technology is the DAB+ technology. These comprise of a transmitter and receiver systems for the transmission of the audio signal in the form of digital radio technology. In this paper, to achieve errorless audio signal the maximum likelihood Viterbi decoder in DAB/DAB+ is designed. The analysis has been carried out along with simulation studies under ModelSim Altera 6.4a that resulted in power and area efficient architecture. In order to show the efficiency of reliable DAB/DAB+ systems, the signal to noise ratio has been tabulated and executed with MATLAB Simulink tool.
