A Communication Channel with Random Battery Recharges Academic Article uri icon


  • Abstract: Motivated by the recent emergence of energy harvesting and wirelessly powered transceivers, we study communication over a memoryless channel with a transmitter whose battery is recharged at random or deterministic times known to the receiver. We characterize the capacity of this channel as the limit of an n-letter maximum mutual information rate under various assumptions: causal and noncausal transmitter knowledge of the battery recharges; with or without feedback from the receiver to the transmitter. While the resultant n-letter …
