We study the arbitrarily varying relay channel, which models communication with relaying in
the presence of an active adversary. We establish the cutset bound and partial decode …

We consider the arbitrarily varying Gaussian relay channel with sender frequency division.
We determine the random code capacity, and establish lower and upper bounds on the …

We consider a three-terminal state-dependent relay channel with the channel state available
noncausally at only the source. Such a model may be of interest for node cooperation in the …

In a relay channel, between the sender X and the the receiver Y lies at least one relay.
Generally, the relay can both transmit its own information and help forwarding other sources' …

In this thesis, we examine the effect of relay memory on the capacity of two types of relay
channels. In the first part of the thesis, we present a parallel relay channel model. Under this …

The simultaneous relay channel is investigated where the source is unaware of the channel
statistic controlling the communication but knows that this statistic is one of two possible …

We investigate the Gaussian relay channel where the additive noises at the relay and
destination are correlated. We obtain achievable rates for the compress-and-forward and …

We consider a relay channel where a relay helps the transmission of messages from one
sender to one receiver. The relay is considered not only as a sender that helps the message …

In this paper, a class of state-dependent relay channel with orthogonal channels from the
source to the relay and from the source and the relay to the destination is studied. The two …

We consider a discrete memoryless relay channel, where both relay and destination may
have an incorrect estimation of the channel. This estimation error is modeled with …
