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.
