摘要

本文提出了一种基于喷泉码的DAB/DMB高效数字广播系统，并设计了一个辅助的移动数据通道，对所有接收方传输数据的完整性进行反馈。该辅助信道还可用于向先前广播的消息解码失败的接收器提供额外的码字。我们还表明，当大量接收器接收相同的信息时，这种组合系统可以成为一种高效的解决方案，例如在户外电子标牌中。

Data broadcasting over DAB/DMB with Fountain codes and auxilliary mobile data channels

In this paper we propose a system for efficient broadcasting of digital data using DAB/DMB with Fountain Codes and an auxiliary mobile data channel to provide feedback about the completeness of the transmitted data by all the receivers. This auxiliary channel can also be used to supply extra codewords to the receivers that failed the message decoding previously brodcasted. We also show that this combined system can be an highly efficient solution when a large number of receivers are expected to receive the same information such as in outdoor electronic signage.
