Abstract

The Digital Audio Broadcasting (DAB) system promises to provide CD-quality sounds and flexible data services to mobile, portable and fixed receivers. In order to achieve high quality in multipath environment, a complicated channel coding and modulation scheme is adopted. This paper presents a channel decoding architecture for DAB test receiver, which accomplishes the functions including program selection, de-multiplexing, time de-interleaving, null symbol insertion into punctured bit-stream and Viterbi decoding. The channel decoder was successfully realized on field programmable gate arrays and Viterbi decoding chips
