In this paper, we derive the capacity of the Gaussian degraded'cheap'relay channel,
consisting of nodes using'cheap'radios operating in TDD mode when transmitting and …

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 …

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 …

Coding strategies that exploit node cooperation are developed for relay networks. Two basic
schemes are studied: the relays decode-and-forward the source message to the destination …

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 …

Two coding strategies are developed for a multiple-relay channel having one source
terminal and one destination terminal. The first strategy mimics multiple-antenna …

We consider a state-dependent three-terminal full-duplex relay channel with the channel
states noncausally available at only the source, that is, neither at the relay nor at the …

We determine the capacity region of a degraded Gaussian relay channel with multiple relay
stages. This is done by building an inductive argument based on the single-relay capacity …

The spectral efficiency of mobile radio networks can be improved by allowing each mobile
station to act as a relay for one other mobile station. One can expect further performance …

The L-user additive white Gaussian noise multiway relay channel is investigated, where L
users exchange information at the same rate through a single relay. A new achievable rate …
