Energy-Efficient Power Allocation for Multi-user Single-DF-Relay Networks

Optimal power allocation for energy‐efficient full‐duplex cognitive relay networks under primary interference

“…Motivated by the need to improve the EE, several authors have recently made attempts to analyse the EE of CRNs, see e.g. [12–22] and references therein. In [12, 13], the authors have independently investigated the optimal power allocation (OPA) scheme for improving the EE of decode‐and‐forward (DF)‐based dual‐hop CRN.…”

“…Sun and Wang [21] have investigated the energy‐efficient power allocation problem in OFDM‐based HDCRNs for maximising the overall EE of the CR system, under the constraints of transmission power budget, traffic demands, and the interference constraints of the PUs. In [22], the authors have investigated OPA strategies to minimise the sum‐power consumption in multi‐user single‐DF relay cooperative networks.…”
