Center node: "finite blocklength achievable rates for energy harvesting awgn channels with infinite buffer"
  Abstract: We consider an additive White Gaussian channel where the transmitter is powered by an energy harvesting source. For such a system, we provide a lower bound on the maximal code book at finite code lengths that improves upon previously known bounds.
