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 present an achievable rate for general Gaussian relay networks. We show that the achievable rate is within a constant number of bits from the information-theoretic cut-set …
We evaluate the information-theoretic achievable rates of Quantize-Map-and-Forward (QMF) relaying schemes over Gaussian N-relay diamond networks. Focusing on vector Gaussian …

Beginning with work by Avestimehr, Diggavi and Tse, there have been a series of papers showing that the capacity of Gaussian relay networks can be closely approximated by the …
R Kolte, A Özgür, A El Gamal - IEEE Transactions on …, 2015 - ieeexplore.ieee.org
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 Gaussian N-relay diamond network, where a source wants to communicate to destination node through a layer of N-relay nodes. We investigate the following question …
M Gastpar, M Vetterli - Proceedings IEEE International …, 2002 - ieeexplore.ieee.org
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 …
X Wu, A Özgür - IEEE Transactions on Information Theory, 2017 - ieeexplore.ieee.org
The cut-set bound developed by Cover and El Gamal in 1979 has since remained the best known upper bound on the capacity of the Gaussian relay channel. We develop a new …
S Brahma, C Fragouli - 2014 IEEE International Symposium on …, 2014 - ieeexplore.ieee.org
We consider a Gaussian diamond network where a source communicates with the destination through n noninterfering half-duplex relays. Using simple approximations to the …
