The performance of simultaneous wireless information and power transfer (SWIPT)-enabled cellular networks by utilizing adaptive modulation are investigated.
In particular, the coverage probability (Pcov), the occurrence probabilities of different mode of modulations and the achievable spectral efficiency (ASE) are provided by leveraging tools from stochastic geometry.
It should be noted that different from works in the literature which are ignored the spatial-correlation between base stations (BSs) as well as the correlation between information decoding and harvested energy at the end-devices (EDs), we take these into considerations by yielding the recent definition of the coverage probability.
Finally, our numerical results show that employing adaptive modulation in SWIPT-enabled ED is a promising way to improve both spectral efficiency (SE) and energy efficiency (EE) of cellular networks.
