DAB (digital audio broadcasting) is a radio system which is depends on EUREKA-147 project. This project was designed by the Members of European Broadcasting Union (EBU). DAB System depends on wireless communication. DAB channel estimation was designed by the OFDM technology that reduces cochannel interference and multipath fading. In this paper we have analyzed bit error rate performance v/s signal to noise ratio (BER v/s SNR).for DAB modes we done block coding with the help of MATLAB Simulink tool. In this paper we use 16-QAM modulation technique and reed-Solomon convolution coding.
