In energy harvesting communication systems, the energy required for message transmission is maintained by an exogenous energy arrival process independent of the message. This links the problem of communication with an energy harvesting transmitter to the problem of communication over state-dependent channels. In particular, if the transmitter has no battery, the available energy can be viewed as a state and the resulting channel is a state-dependent channel with causal state information at the transmitter only. In general, information transmission blurs the state information that the receiver can get from the received signal.
