In many known examples where compress-and-forward (CF) for relay networks is capacity
achieving, it is only trivially so, ie, it falls back to hashing without quantization. A potentially …

In this paper, we present a new generalization of the well-known Compress-and-Forward
strategy for relay networks. We propose an offset decoding at destination, where destination …

We study a special class of diamond channels which was introduced by Schein in 2001. In
this special class, each diamond channel consists of a transmitter, a noisy relay, a noiseless …

Consider a Gaussian relay network where a source node communicates to a destination
node with the help of several layers of relays. Recent work has shown that compress-and …

We consider the-relay Gaussian diamond network where a source node communicates to a
destination node via parallel relays through a cascade of a Gaussian broadcast (BC) and a …

We determine the asymptotic capacity of a Gaussian multiple-relay channel as the number
of relays tends to infinity. The upper bound is an application of the cut-set theorem, and the …

We consider the Gaussian “diamond” or parallel relay network, in which a source node
transmits a message to a destination node with the help of N relays. Even for the symmetric …

This work investigates the optimality of compress-and-forward (CF) type relaying in wireless
networks when the relay does not know the codebooks used by the sources. The relay is …

We study a wireless relay network, with a single source and a single destination. Our main
result is to show that an appropriate compress-and-forward scheme supports essentially the …

Noisy network coding is recently proposed for the general multi-source network by Lim, Kim,
El Gamal and Chung. This scheme builds on compress-forward (CF) relaying but involves …
