Maximum Transmission Rate of PSR/TSR Protocols in Wireless Energy Harvesting DF-Based Relay Networks
IEEE Journal on Selected Areas in Communications (JSAC), Volume 33, Issue 12Pages 2701–2717https://doi.org/10.1109/JSAC.2015.2481213In this paper, we consider the power splitting relaying (PSR) and time switching relaying (TSR) protocols for decode-and-forward (DF)-based relay networks consisting of a source, a relay, and a destination. For the networks, the relay is assumed to have a ...

Two-way amplify and forward relaying with adaptive modulation
IWCMC '09: Proceedings of the 2009 International Conference on Wireless Communications and Mobile Computing: Connecting the World WirelesslyPages 1370–1374https://doi.org/10.1145/1582379.1582680Cooperative diversity has been recently presented as a new technique to improve the link performance of wireless communication systems. However, a loss in spectral efficiency due to half-duplex relaying can be a significant weak-point for high data rate ...

Performance analysis of incremental opportunistic relaying over identically and non-identically distributed cooperative paths
IEEE Transactions on Wireless Communications (TWC), Volume 8, Issue 4Pages 1953–1961https://doi.org/10.1109/TWC.2009.080381In this paper, we consider an incremental relaying protocol based on an amplify-and-forward transmission in conjunction with the best relay selection scheme over nonidentically distributed relay channels. In order to satisfy the spectral efficiency and ...

Switch-and-examine node selection for efficient relaying systems
IWCMC '07: Proceedings of the 2007 international conference on Wireless communications and mobile computingPages 469–474https://doi.org/10.1145/1280940.1281041The opportunistic relaying in [1] was proposed as an efficient cooperative protocol in the wireless multi-hop systems. However, the opportunistic relaying may still have high complexity as the number of relay nodes increases since the link quality of ...
