Abstract
The wireless channel is a hostile environment. The transmitted
signal does not only suffers multi-path fading but also noise and
interference from other users of the wireless channel. That causes
unreliable communications. To achieve high-quality communications,
error correcting coding is required to mitigate the noise and
interference encountered during the signal transmission. However,
the current design of error correcting codes does not take the power
consumption in ADCs into account. ADCs consume about 50\% of the
total base-band power. The power-efficiency of ADCs does not
increase in the same speed as the baseband signal processing.
Digital signal processing follows Moore's law. Given the same
specification, the power consumed in ADCs halves every 2.7 years but
the power consumption in the baseband signal processing decreases a
factor of 10 every 5 years. In the case of RF signal processing, the
power efficiency is limited by the semi-conductor technology.
Therefore, ADCs are the main bottleneck for an energy-efficient
wireless receiver.
