On the asymptotic capacity of Gaussian relay networks

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 …

Approximate capacity of Gaussian relay networks

AS Avestimehr, SN Diggavi… - 2008 IEEE International …, 2008 - ieeexplore.ieee.org
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 …

Cut-set bound is loose for Gaussian relay networks

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 …

Amplify-and-forward in wireless relay networks

S Agnihotri, S Jaggi, M Chen - 2011 IEEE Information Theory …, 2011 - ieeexplore.ieee.org
A general class of wireless relay networks with a single source-destination pair is
considered. Intermediate nodes in the network employ an amplify-and-forward scheme to …

Approximate capacity of Gaussian relay networks: Is a sublinear gap to the cutset bound plausible?

TA Courtade, A Özgür - 2015 IEEE International Symposium on …, 2015 - ieeexplore.ieee.org
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 …

On the capacity of large Gaussian relay networks

M Gastpar, M Vetterli - IEEE Transactions on Information …, 2005 - ieeexplore.ieee.org
The capacity of a particular large Gaussian relay network is determined in the limit as the
number of relays tends to infinity. Upper bounds are derived from cut-set arguments, and …

Capacity of a class of multi-source relay networks

SW Jeon, SY Chung - 2009 Information Theory and …, 2009 - ieeexplore.ieee.org
We consider a relay network having K source-destination pairs. Finding the capacity region
of such a network with multiple unicast sessions is in general difficult. By focusing on a …

Capacity approximations for Gaussian relay networks

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 …

[PDF][PDF] Lower bounds on the capacity of Gaussian relay channel

MA Khojastepour, A Sabharwal… - Proc. Annu. Conf …, 2004 - repository.rice.edu
It has been shown recently that the overall throughput of dense wireless networks can
increase significantly when wireless nodes collaborate in transmission of different packets …
