Impact of Overhearing Link Quality on Power Allocation Strategy and Relay Location for Analog Network Coding

Outage performance analysis of wireless energy harvesting‐based two‐unicast networks

“…In [12, 13], the average sum rate and outage probability were studied for a two‐unicast network, in which two source–destination pairs accomplish communications via the same AF‐based relay node with the constant power supply. Lee et al [14] studied the impact of the quality of overhearing links on the sum rate of the two‐unicast network. Compared to the conventional scheme, in which each source–destination pair one after another accomplishes communications with the help of the relay node, the two‐unicast network can increase the system throughput for saving the transmission time.…”

Approximate capacity of symmetric two‐pair one‐way relay channel with overhearing links

“…This channel model is a variant of TPOWRC, with only difference in the existence of the cross pair OLs. Many papers have research similar to network models [6–11]. In [6], another variant of two‐pair one‐way relay network adding the direct links in source–destination (SD) pairs and the OLs in the cross pairs is studied.…”

“…The network model in [6] is extended to multiple SD pairs in [7–9]. In [10, 11], the TPOWRC‐OLs is studied. The authors in [10] propose a rate and power adaption scheme for maximising the minimum data rate and the channel conditions of the OLs have been considered, but they assume the interference signal can be removed from each destination completely.…”

“…The authors in [10] propose a rate and power adaption scheme for maximising the minimum data rate and the channel conditions of the OLs have been considered, but they assume the interference signal can be removed from each destination completely. In [11], the residual interference at each corresponding destination is considered according to the channel quality of the OLs while the authors investigate the impact of the channel quality of OLs on the power allocation strategy and relay location. From [10, 11], it can be seen that OLs act as a key role on the system performance of TPOWRC‐OLs.…”

“…In [11], the residual interference at each corresponding destination is considered according to the channel quality of the OLs while the authors investigate the impact of the channel quality of OLs on the power allocation strategy and relay location. From [10, 11], it can be seen that OLs act as a key role on the system performance of TPOWRC‐OLs. As a result, an interesting question that arises is how the channel quality of the OLs affects the capacity of this channel model.…”
