Abstract:
|
An energy harvesting transmitter operating in a point-to-point link through a discrete time fading channel is considered in this paper. Assuming non-causal knowledge of the harvested energy and channel state, the resource allocation that maximizes the mutual information is investigated by considering both the radiated power and the circuitry power consumption. A resource allocation strategy that asymptotically maximizes the mutual information along N independent channel accesses is derived. The Boxed Water-Flowing graphical interpretation is presented, which intuitively depicts the asymptotically optimal resource allocation. |
