Abstract:	The current error correction layer of IEEE 802.11a WLAN 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. The key part in the new proposed system is that only packets are processed by the receiver chain which have encountered ``good'' channel conditions. Others are discarded. With this new approach, around $\frac{2}{3}$ of the energy consumption can be saved compared with the conventional IEEE 802.11a WLAN system under the same channel conditions and throughput.
