Power Efficiency in Communication Systems From a Circuit Perspective
The authors consider the minimization of the overall power consumption when communicating over a noisy single-input single-output channel while satisfying a certain throughput and error rate constraint. The total power dissipation includes the radiated power as well as the circuit power consumption. In the context of battery operated short range communication, where low power, low cost and small size are key requirements (e.g. standard IEEE 802.15.4), this circuit aware system optimization is crucial given the growing importance of "Green Communication". In fact, the power dissipation of certain analog and digital components along the signal path reaches values in the order of or is even higher than the transmit power in such applications.
