“…Define Q k = V H Q k V(∀k) for notational brevity. Following a similar proof procedure as that in [34], [50], we can obtain that Q k should be diagonal for all k to maximize η SE in (11) and η EE in (14). Besides, the off-diagonal elements of Q k (∀k) do not affect the value of k tr {Q k } and thus do not affect the power consumption term P sum in (12).…”

“…In addition to the SE, energy efficiency (EE) also has gained wide research attention for the design of wireless networks [18,19]. Energy constraints introduce an upper limit on the power of transmission and associated signal processing in wireless devices, especially for batterypowered equipments [20].…”

“…According to the signal partition method for EH and ID, there are mainly two types of practical SWIPT receiver designs, namely the time-switching (TS) and the powersplitting (PS) receiver architectures [18]. The TS receiver alternately switches between EH and ID according to the TS ratio [36].…”

“…In an actual simultaneous wireless information and power transfer (SWIPT) system [13], the base station (BS) or access point (AP) provides the receiver with concurrent information and energy supply. Currently, the practical SWIPT receiver architecture can be mainly classified as time-switching (TS) and powersplitting (PS) [14] according to the signal partition method for EH and information decoding (ID). The TS SWIPT receiver alternates between EH and ID according to the TS ratio [15], and as a result, the received RF signal is first sent to the energy harvester and then to the information decoder.…”
