Simultaneous wireless information and power transfer (SWIPT) technique is a popular strategy to convey both RF energy for harvesting at receivers. In this regard, we consider two-way relay system with multiple users multi-antenna employing SWIPT strategy, where splitting the received signal leads rate-energy trade-off. literature, works on transceiver design have been studied using computationa...

Compute-and-forward relaying is effective to increase bandwidth efficiency of wireless two-way relay channels. In a compute-and-forward scheme, a relay tries to decode a linear combination composed of transmitted messages from other terminals or relays. Design for error correcting codes and its decoding algorithms suitable for compute-and-forward relaying schemes are still important issue to be...

© 2013 ETRI Journal, Volume 35, Number 2, April 2013 To enhance the symbol error rate (SER) performance of the two-way relay channels with physical layer network coding, this letter proposes a relay selection scheme, in which the relay with the maximal minimum distance between different points in its constellation among all relays is selected to assist two-way transmissions. We give the closed-...
