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 …

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 …

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 …

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 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 …

We provide achievable rate regions for two-way relay channels (TRC). At first, for a binary
TRC, we show that the subspace-sharing of linear codes can achieve the capacity region …

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 …

We present a new physical layer network coding (PLNC) scheme, called superimposed
XOR, for two-way relay channels. The new scheme specifically takes into account the …

This paper addresses the design of irregular repeat accumulate (IRA) codes for coded
physical-layer network coding (PNC) for the binary-input Gaussian two-way relay channel …

We propose and design a practical modulation-coded (MC) physical-layer network coding
(PNC) scheme to approach the capacity limits of Gaussian and fading two-way relay …
