Energy efficiency of decode-and-forward full- duplex relay channels

Performance Analysis of a Full-Duplex MIMO Decode-and-Forward Relay System With Self-Energy Recycling

“…where α is the isolating factor, and P c0 comprises of all other constant power consumption in the analog and digital SI cancellation circuit [49]. Thus, the total circuit power consumption of FD relay system can be expressed as…”

“…The AEE for adaptive S-ER scheme, AEE adp e2e , as defined in (21) can now be evaluated by utilizing (27), (28), and (49). Hence, it can be written as…”

Spectrum-Energy Efficiency Tradeoff in Decode-and-Forward Two-Way Multi-Relay Networks

“…In literature, a large number of works have been studied on different relay networks focusing on EE or SE. In [7], an optimal power allocation scheme is studied to enhance EE of a DF full-duplex (FD) relay channel, considering the extra circuit power consumption. In [8], the performance of joint power allocation and bandwidth sharing of an FD relay network is investigated.…”

“…In [12] [13], spatial modulation (SM) has been proposed to increase the EE compared with that of the conventional multiple-input multiple-out (MIMO) technique. However, schemes in [7]- [13] are not suitable for the situation where SE is taken into account. In [14], a joint transmission beamforming design, user grouping, time allocation, and power allocation scheme is designed for maximizing SE of FD systems.…”

Spectral–energy efficiency tradeoff in decode‐and‐forward full‐duplex relay system

“…In [10], the EE optimisation problem of FD and HD relaying mode with AF protocol were analysed and compared. In [11], the EE maximisation of FD DF relaying protocol is transformed into a max–min problem and the EE of FD mode was compared both with HD mode and DT. It transforms the max–min problem to a maximisation of a new function which is a fractional form and adopt the fractional programming technique to transform the objective function to a subtractive form.…”
