We consider the problem of relay selection in a network with N relay nodes. A half-duplex
relay node enables bidirectional communication between two nodes with a spectrally …

We consider the problem of jointly optimizing channel pairing, channel-user assignment,
and power allocation in a single-relay multiple-access system. The optimization objective is …

Two-way relaying has demonstrated significant gain in spectral efficiency by applying
network coding when a pair of source nodes exchange information via a relay node. This …

Optimal power allocation schemes that maximize the instantaneous received signal-to-noise
ratio in an amplify-and-forward multi-hop transmission system under short-term (ST) and …

We study the problem of channel pairing and power allocation in a multichannel multihop
relay network to enhance the end-to-end data rate. Both amplify-and-forward (AF) and …

We obtain the achievable beamforming rate region for a two-way cooperative network
consisting of two transceivers and multiple relays, all single-antenna nodes. Assuming that …

In this paper, we design a multiuser two-way relay system using space division multiple
access (SDMA) communications and devise an optimal scheduling method that maximizes …

This Letter analyzes the outage performance of a multiuser bidirectional cooperative cellular
network in which one base station (BS) and one out of N mobile stations (MSs) exchange …

We investigate the performance of multi-antenna two-way relay networks, where both
amplify-and-forward (AF) and decode-and-forward (DF) relaying strategies are considered …

This paper considers a two-way half-duplex decode-and-forward relaying system, where
multiple pairs of single-antenna users exchange information via a multiple-antenna relay …
