Modeling the Energy Harvested by an RF Energy Harvesting System Using Gamma Processes [PDF]

Mathematical Problems in Engineering, 2019
In an Energy Harvesting system (EHS) the gamma process is used to model the electromagnetic energy received from radiofrequency (RF) radiation. The stochastic characterization of the harvested energy as a continuous‐time stochastic process, namely, gamma process, is obtained from the Nakagami‐m fading model, which describes the signal reception in a ...
