With the rapid growth of wireless data traffic and antennas configuration, higher spectrum
efficiency and lower power consumption processing have evoked remarkable attention from …

Network coding (NC) is a technique used for effective and secure communication by
improving the network capacity, throughput, efficiency, and robustness. In NC, data packets …

Focusing on two-antenna infrastructure relays employed for coverage extension, we
develop hybrid techniques that switch opportunistically between full-duplex and half-duplex …

This paper investigates the performance of practical physical-layer network coding (PNC)
schemes for two-way relay channels. We first consider a network consisting of two source …

The multiuser communication channel, in which multiple users exchange information with
the help of a relay terminal, termed the multiway relay channel (mRC), is introduced. In this …

In this paper, we address the security of a two-way relay network in the presence of an
eavesdropper, where each node is only equipped with single antenna. We propose two …

The full duplex (FD) technique, which allows the communication node to transmit and
receive signals over the same frequency band simultaneously, has the potential to double …

In this paper, we propose a hybrid cooperative beamforming and jamming scheme to
enhance the physical-layer security of a single-antenna-equipped two-way relay network in …

In this paper, we propose a relay selection amplify-and-forward (RS-AF) protocol in general
bidirectional relay networks with two sources and N relays. In the proposed scheme, the two …

In this paper, we investigate the performance of multi-pair two-way relaying, in which
multiple pairs of users exchange information within pair, with the help of a shared relay …
