In many wireless systems, the energy consumed by the receiver is significantly larger than the energy consumed by transmitter, possibly even by orders of magnitudes. This paper derives an analytical solution to maximize the throughput per unit of available receiver circuit power. Adaptive control of the IP3, to handle the time-varying adjacent channel interference level, can substantially improve the power efficiency, compared to the common practice of design for worst case. There appears to be an optimum throughput at a specific (non zero) power consumption level. For large SNR, the optimal throughput per Joule of receiver circuit power occurs for a modulation rate of 2.3 bits/s/Hz, irrespective of interference power level. If the receiver has less power available than the optimum setting requires, a duty cycling scheme can still achieve optimum operation.
