“…An appropriate NC employment at the relay nodes could save bandwidth for a higher system throughput. Many NC-based protocols have been proposed and investigated for particular relay topologies such as relay-assisted bidirectional channels [16], broadcast channels [17], multicast channels [18], unicast channels [19] and vehicular networks [20], [21]. As a specific model of multicast channels, butterfly networks have been investigated, e.g.…”

“…Researchers have also been dedicated to investigating the application of network coding (NC) [8], [9] to improve the network throughput of some particular relay topologies, such as relayassisted broadcast channels [10], [11], multicast channels [12], [13], unicast channels [14], [15], and bidirectional channels (i.e., TWSRNs) [16], [17]. Here, we investigate the application of NC to TWSRNs, which have interested many studies [18]- [23].…”

This results in a significant improvement of system throughput especially when the number of relays is large. Upper and lower bounds of the mean square error (MSE) of the estimated CQI are derived to study performance behaviour of our proposed scheme. It is found that the MSE of the estimated CQI increases proportionally with the square of the cardinality of CQI level sets though an increased number of CQI levels would eventually lead to a higher data-rate transmission. Based on the derived bounds, a low-complexity relay selection (RS) scheme is then proposed. Simulation results show that, in comparison with optimal methods, our suboptimal bound-based RS scheme achieves satisfactory performance while reducing the complexity at least three times in case of large number of relays.Quoc-Tuan Vien is with School of Engineering and Built Environment,

“…The basic concept of NC is that the relays perform algebraic linear/logic operations on received packets from multiple transmission sources in order to create a new combined packet, which is then forwarded to 2 the destination nodes in the subsequent transmission. Various NC-based protocols have recently been proposed for some particular relay channel topologies such as relay-assisted bidirectional channels [8], broadcast channels [9], multicast channels [10] and unicast channels [11].…”
