We consider a communication system where two transmitters wish to exchange information
through a central relay. The transmitter and relay nodes exchange data over synchronized …

We consider the problem of two transmitters wishing to exchange information through a
relay in the middle. The channels between the transmitters and the relay are assumed to be …

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 …

This paper investigates link-by-link channel-coded PNC (physical layer network coding), in
which a critical process at the relay is to transform the superimposed channel-coded packets …

It has recently been recognized that the wireless networks represent a fertile ground for
devising communication modes based on network coding. A particularly suitable application …

This paper considers a wireless relay network where two nodes S1 and S2 exchange their
information through a relay node RL. It is assumed that both S1 and S2 are equipped with …

In this paper, we study a decode-and-forward two-way relaying network. We propose an
opportunistic two-way relaying (O-TR) scheme based on joint network coding and …

In this paper, we propose a network coding using a lattice for the two-way relay channel with
two nodes communicating bidirectionally through a relay, which we call modulo-and-forward …

We investigate modulation schemes optimized for two-way wireless relaying systems, for
which network coding is employed at the physical layer. We consider network coding based …

Lattice codes are known to achieve capacity in the Gaussian point-to-point channel,
achieving the same rates as iid random Gaussian codebooks. Lattice codes are also known …
