The paper investigates the effect of link delays on the capacity of relay networks. The relay-
with-delay is defined as a relay channel with relay encoding delay d isin Z of units, or …

A relay-without-delay channel in which each transmitted relay symbol can depend on all its
past as well as present received symbols is investigated. A general upper bound on the …

Relay transmissions can help improve system coverage and throughput, and hence
information-theoretic analysis of relay channels has been at the forefront of research for …

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 …

The capacity of a class of deterministic relay channels with the transmitter input X, the
receiver output Y, the relay output Y 1= f (X, Y), and a separate communication link from the …

We consider the communication problem in a multi-hop relay network where the
intermediate relay nodes cannot transmit and receive at the same time. The motivation for …

A relay channel consists of an input x_ l, a relay output y_ 1, a channel output y, and a relay
sender x_ 2 (whose transmission is allowed to depend on the past symbols y_ 1. The …

The capacity of a class of deterministic relay channels with transmitter input X, receiver
output Y, relay output Y 1= f (X, Y), and separate noiseless communication link of capacity R …

The capacity region of multi-pair bidirectional relay networks, in which a relay node
facilitates the communication between multiple pairs of users, is studied. This problem is first …
