Abstract:The current error correction layer of digital mobile TV is designed for worst case scenarios, which often do not apply. In this paper, we propose a new opportunistic error correction layer based on fountain codes and a resolution adaptive ADC, which has been integrated into the OFDM-based physical layer. The key element in the new proposed system is that only packets are processed by the receiver which have encountered high-energy channels. Others are discarded. With this new approach, around 84% of the energy consumption in ADCs can be saved compared with the conventional mobile TV system under the same channel conditions.
