【Program doc】 DABreceiver DL : 0: DAB接收机，包括信道解码的资料。DAB系统中载波频偏估计等。 -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 deinterleaving, null symbol insertion into punctured bitstream and Viterbi decoding. The channel decoder was successfully realized on field programmable gate arrays and Viterbi decoding chips.

【Software Engineering】 vm DL : 0: Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum data shows stable for watermark hiding by the methods of edging data cutting and statistical mean modification. The synchronization is not required in the algorithm. Experimental results show that the proposed algorithm can resist on the attack of A/D and D/A successfully with features of large capacity and zero bit error. It will be helpful for the mobile audio in secure broadcast and management in the
