A total power minimization approach to relay selection for two-way relay networks

Performance analysis of full‐duplex cellular two‐way relay networks with the Nth worst relay selection under channel estimation error and cochannel interference

“…Related Works: The integration of multiple relays in the TWR system has shown promising results. Talwar and Panahi 9 have proposed relay selection schemes to improve the system throughput. Pang et al 10 have developed a relay selection technique based on physical layer network coding to improve the sum rate of the system.…”

“…The energy-efficient relay selection in nonregenerative relay-based orthogonal frequency-division multiple access systems have been examined in the work of Chen et al 12 Moreover, Park et al 13 have studied two-phase and three-phase ANC schemes for orthogonal frequency division multiplexing-based TWR networks with multiple relays. It should be noted that all the aforementioned works [9][10][11][12][13] have considered that each relay in the system works with half-duplex (HD) capability. Very recently, various relay selection schemes have been examined for an FD-based TWR networks with multiple relay nodes.…”

“…• We also deduce the asymptotic analysis for the OOP and ABER in the high SNR regime. Using asymptotic outage expression, we present some practical cases of interest to highlight the effect of CEE, CCI, and residual self-interference 6,7 No No Full-duplex Multiuser TWR None Fidan and Kucur 8 No No Full-duplex Multiantenna TWR None Other works [9][10][11][12][13] No No Half-duplex Multirelay TWR Best relay selection Other works [14][15][16][17][18][19][20][21] No No Full-duplex Multirelay TWR Best relay selection Other works [22][23][24][25][26] No No Half-duplex Multirelay TWR Nth Best relay selection Yang et al 27 No…”
