This paper studies the wireless two-way relay channel (TWRC), where two source nodes, S1
and S2, exchange information through an assisting relay node, R. It is assumed that R …

Recently, it has been shown that a quantize-map-and-forward scheme approximately
achieves (within a constant number of bits) the Gaussian relay network capacity for arbitrary …

Abstract In [1], a new relaying strategy, quantize-map-and-forward (QMF) scheme, has been
demonstrated to approximately achieve (within an additive constant number of bits) the …

In a recent work, Nazer and Gastpar proposed the compute-and-forward strategy as a
physical-layer network coding scheme. They described a code structure based on nested …

This paper deals with the problem of multicasting a set of discrete memoryless correlated
sources (DMCS) over a cooperative relay network. Necessary conditions with cut-set …

We consider the symmetric discrete memoryless relay channel with orthogonal receiver
components and show that polar codes are suitable for decode-and-forward and compress …

The non-binary code (NBC) or the lattice code (LC) has been the only possible channel
code with the pulse amplitude modulation (PAM) signaling of modulation size greater than …

A decode-and-forward LDPC-based coding and decoding scheme is proposed and applied
to the BAWGN single-relay channel. The source broadcasts information to both the relay and …

Quantize-map-and-forward (QMF) is a relaying scheme that has been shown to achieve the
capacity of Gaussian relay networks to within a constant gap. Under QMF the compression …

This paper describes a methodology for efficient implementation of binning and block-
Markov coding for the relay channel using powerful features of low-density parity-check …
