### Abstract

Maximizing the battery life time of mobile devices
and sensor nodes increasingly becomes a challenge. In many
applications the energy consumed by the receiver is orders of
magnitude larger than the energy consumed by the transmitter.
We address the challenge of achieving the highest possible
throughput per Watt of available receiver circuit power. Our
closed form solution allows us to formalize the relation between
adjacent channel interference power and achievable throughput
for a given available receiver circuit power budget. We conclude
that for a given adjacent channel interference level, there is an
optimum receiver power that needs to be applied to operate
the link at optimum efficiency in terms of bits per Joule. If the
receiver has less power available than this optimum, it preferably
applies a duty cycling scheme, switching between an off state and
operation at the optimum power. This observation is contrast to
commonly used capacity models where throughput is limited by
transmit power.
