Analysis and Design of Rateless Two-way Relay Networks Based on a Multiply-and-Forward Scheme

“…In [14], Xu et al proposed a multiply-and-forward (MF) approach, in which the relay multiplies the signals sent from different source nodes. More importantly, MF has shown a significant performance increase compared to AF in a three-stage TWRN system [14][15][16][17].…”

Energy Efficiency Maximization for SWIPT Enabled Two-Way DF Relaying

“…In [7], the authors studied the optimal PS/TS ratio for the one-way amplify-and-forward (AF) relay network with a non-linear EH model. Since two-way relaying achieves a higher spectral efficiency, SWIPT enabled two-way relaying has attracted extensive interests [8], [9]. In [8], the authors studied the Personal use of this material is permitted.…”

“…Liqin Shi achievable throughput of SWIPT enabled AF two-way relaying under three wireless power transfer policies. Authors in [9] proposed an optimal asymmetric PS scheme for the SWIPT enabled product two-way AF relaying network to minimize the system outage probability. Recall that EE has become an emerging important metric in future wireless networks, the EE was maximized by optimizing both precoding matrices and the PS ratio for SWIPT enabled multiple-input-multiple-output (MIMO) two-way AF networks [10], [11].…”

“…For the information processing, the received achievable rate at R from node i is given by τ iR = 2 The assumption of perfect CSI can obtain the upper bound of performance for our considered network. Thus, there are also many state-of-art works [9]- [11], [13], which are studied based on the assumption of perfect CSI. This motivates us to consider the assumption of perfect CSI.…”

“…where P R = E total (1−2β)T is the transmit power at R; n i = n i ∼ CN 0, W σ 2 is the AWGN at i; step (a) follows by using SIC [8], [9];ī denotes the index of the other destination node. Based on (3), the achievable rate at i from R is given by…”
