Processing-to-amplifier power ratio for energy efficient communications
Electronics Letters, 2012 The energy consumption of modern communications systems is dominated by the signal processing and shaping circuitry. Assuming a rate-independent processing power consumption, the energy per bit spent for signal processing can be effectively reduced by increasing the transmission power.
