Abstract

In [1] we have proposed a novel cross-layer scheme based on resolution adaptive ADCs and fountain codes for the OFDM systems to lower the power consumption in ADCs. The simulation results show that it saves more than 70% power consumption in ADCs comparing to the current IEEE 802.11a system.In this paper, we investigate its performance in the real-world. Measurement results show that the FEC layer used in the IEEE 802.11a system consumes around 59 times of the amount of power in ADCs comparing to the LDPC codes from the IEEE 802.11n standard, whose power consumption in ADCs is around 26 times of the proposed cross-layer method. In addition, this new cross-layer approach only needs to process the well-received packets to save the processing power. The latter can not be applied in the current FEC schemes.
