Abstract-Digital Audio Broadcasting (DAB) is an amazing technology, achieving its promise of certainly delivering high quality digital audio in the most vindicate mobile and fixed receiver environments. In this paper, the dissection of Bit Error Rate (BER) for Digital Audio Broadcasting (DAB) process with different channel coding techniques using Coded Orthogonal frequency division multiplexing (C-OFDM) in Matlab-Simulink Environment. The interpretation is carried out for convolution and turbo codes in an Additive White Gaussian Noise Channel (AWGN) depending on code generator polynomials with distinct constraint lengths. Finally, at a certain point the intricacy of the decoder is so high that it becomes tough to execute and also there is no considerable reduction in BER. In addition the coding gain is possible with turbo codes with affordable coding and decoding complexity with reduction in BER. BER for a finest music signal is considered to be 10 -3.5 by using turbo coding, it is approximately achieved with an E b /N o of 7 dB is attained using turbo coding, when distinguish with convolution coding which features high computational complexness.
