|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
of the energy consumption can be saved compared with the
conventional IEEE 802.11a WLAN system under the same channel
conditions and throughput.
