“…In order to proceed with the analysis, we have to take into consideration that the number of activated rectifiers depends on the received RF power signal. As such, we herein calculate the optimum number of the activated rectifiers for the DC combiner at each receive antenna i, following the steps from [23].…”

“…The authors in [22], adopt the beamforming matrix in a hybrid power combining rectenna array. While, in [23] authors consider a single-input multiple-output (SIMO) topology where each receive antenna is connected to multiple rectifiers. We herein, adopt this technique, studying both DC and RF combining schemes, differentiating this way from the conventional rectennas solutions.…”

Smart devices and their applications led to a rapid evolution of the Internet of Things. As a result, there is an emerging need on energizing those low-power devices, while at the same time achieving information transfer. In this context, simultaneous wireless information and power transfer (SWIPT) is considered as an appealing technology, since it can power wirelessly and remotely such devices, simultaneously with information transfer. Motivated by this, we herein propose a system model with an integrated SWIPT receiver, succeeding enhanced performance in terms of information decoding (ID) and energy harvested (EH). Specifically, we adopt a single input multiple output topology, where at the receiver's side we examine two antenna architectures, one based on the direct-current (DC) combining and the other on the radio-frequency (RF) combining. For both schemes, we consider multiple receive antennas and rectifiers, comparing their performances. Furthermore, we adopt a piece-wise linear EH model, which takes into account the sensitivity and saturation effects of the rectifiers. By using a maximum likelihood-based soft decoding, a non-coherent energy detection is achieved. Finally, an asymptotic analysis is conducted, providing upper and lower bounds for ID and EH, respectively. Simulation results along with theoretical analysis, validate the enhanced performance both in terms of ID and EH.
