Capacity bounds and power allocation for wireless relay channels

by Anders Høst-madsen, Junshan Zhang - IEEE TRANS. INF. THEORY , 2005
"... We consider three-node wireless relay channels in a Rayleigh-fading environment. Assuming transmitter channel state information (CSI), we study upper bounds and lower bounds on the outage capacity and the ergodic capacity. Our studies take into account practical constraints on the transmission/rece ..."

Fading relay channels: Performance limits and space-time signal design

by Rohit U. Nabar, Helmut Bölcskei, Felix W. Kneubühler - IEEE J. SELECT. AREAS COMMUN , 2004
"... Cooperative diversity is a transmission technique where multiple terminals pool their resources to form a virtual antenna array that realizes spatial diversity gain in a distributed fashion. In this paper, we examine the basic building block of cooperative diversity systems, a simple fading relay ch ..."

channel where the source, destination and relay terminals are each equipped with single antenna transceivers. We consider three different TDMA-based cooperative protocols that vary the degree of broadcasting and receive collision. The relay terminal operates in either the amplify-and-forward (AF

The multi-way relay channel

by Deniz Gündüz, Aylin Yener, Andrea Goldsmith, H. Vincent Poor - in Proc. IEEE Int. Symposium on Inf. Theory (ISIT), Seoul, Korea
"... Abstract—The multi-user communication channel, in which multiple users exchange information with the help of a single relay terminal, called the multi-way relay channel, is considered. In this model, multiple interfering clusters of users communicate simultaneously, where the users within the same c ..."

On the Capacity of Gaussian Relay Channels ∗

by Shao-lun Huang, Ming-yang Chen, Kwang-cheng Chen, John M. Cioffi , 2008
"... Determining the capacity of Gaussian relay channels even with one relaying station has been an open problem for several decades. This paper presents a pair of upper and lower bounds whose gap is no more than 0.5 bit per channel use, for the capacity of Gaussian relay channels with one relaying stati ..."

Mismatched Decoding for the Relay Channel

by Charlotte Hucher, Parastoo Sadeghi
"... Abstract — We consider a discrete memoryless relay channel, where both relay and destination may have an incorrect esti-mation of the channel. This estimation error is modeled with mismatched decoders. In this paper, we provide a lower-bound on the mismatch capacity of the relay channel. Moreover, w ..."

Error Exponents for the Relay Channel

by Vincent Y. F. Tan
"... Abstract—Achievable error exponents for the relay channel are derived using the method of types. In particular, two block-Markov coding schemes are analyzed: partial decode-forward and compress-forward. The derivations require combinations of the techniques in the proofs of the packing lemma for the ..."

Multihop diversity in wireless relaying channels

by John Boyer, Student Member, David D. Falconer, Halim Yanikomeroglu - IEEE Trans. on Communications
"... Abstract—This paper presents theoretical characterizations and analysis for the physical layer of multihop wireless communications channels. Four channel models are considered and developed: the decoded relaying multihop channel; the amplified relaying multihop channel; the decoded relaying multihop ..."
