Abstract

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. The optimal relation between processing and transmission power for energy efficient communications is derived. This relation is called processing-to-amplifier power ratio (PrAPR).
