The degrees of freedom of compute-and-forward

U Niesen, P Whiting - IEEE Transactions on Information Theory, 2012 - ieeexplore.ieee.org
We analyze the asymptotic behavior of compute-and-forward relay networks in the regime of
high signal-to-noise ratios. We consider a section of such a network consisting of K …

Distributed decode–forward for relay networks

SH Lim, KT Kim, YH Kim - IEEE Transactions on Information …, 2017 - ieeexplore.ieee.org
A new coding scheme for general N-node relay networks is presented for unicast, multicast,

approximate solutions accompanied by universal guarantees on the gap to optimality, in …

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 …
