In the optimization of energy harvest ,some paper want to maximize the harvested power ,rate or minimize the transmitted power,so when they write the formula of optimization,they may assume the beamforming,transmitted power power splitter ,power allocation as variable.
However,i am confused that why there is no one assume the "consumption of circuit" as variable ? All of paper are either assume it is a constant value or just ignore them.
Does anyone know or have a good explanation about we don't assume "consumption of circuit" as variable?
In my opinion,i think the purpose of optimizing something in the energy harvesting is that we want to let the life of battery become longer when we "transmit" the signal correctly,so we will focus on something which has a relation with the transmitted power,like SNR or power splitter,beamforming direction,etc.
Does anyone know or have a better explanation about it?Because we do need a circuit to transmit the signal,and the signal does consumpt the power
