Cooperative transmit diversity based on superposition modulation
TL;DR: A new strategy for cooperative transmit diversity based on superposition modulation and multiuser detection is proposed that can outperform "classical" cooperative Diversity based on decode-and-forward by about 1.5-2 dB in the SNR range of interest and at the same computational complexity.
Journal ArticleDOI
An overview of cooperative communications
TL;DR: This article visits cooperative techniques, such as relay, distributed antennas systems (DAS), multicell coordination, Group Cell, Coordinated Multiple Point transmission and reception (CoMP), those turn the traditional cellular system into a cooperative system.

TL;DR: For a theory to truly characterize the limits of deployed MANETs it must overcome three key roadblocks, spatial and timescale decompositions have not yet been developed for optimally modeling the spatial and temporal dynamics of wireless networks.

Scaling Laws for Ad-Hoc Wireless Networks: An Information Theoretic Approach
Feng Xue,P. R. Kumar +1 more
TL;DR: This monograph addresses questions of how much information transfer they can support, as well as what the appropriate architectures and protocols are for operating them by presenting various models and results that quantify the information transport capability of wireless networks.

Noiseless coding of correlated information sources
David Slepian,Jack K. Wolf +1 more
TL;DR: The minimum number of bits per character R_X and R_Y needed to encode these sequences so that they can be faithfully reproduced under a variety of assumptions regarding the encoders and decoders is determined.
Journal ArticleDOI
Three-terminal communication channels
TL;DR: A coding theorem and weak converse are proved and a necessary and sufficient condition for a positive capacity is derived and upper and lower bounds on the capacity are obtained, which coincide for channels with symmetric structure.

Source coding with side information and a converse for degraded broadcast channels
Rudolf Ahlswede,János Körner +1 more
TL;DR: In Section H of the paper, a characterization of the capacity region for degraded broadcast channels (DBC's) is given, which was conjectured by Bergmans and is somewhat sharper than the one obtained by Gallager.
Journal ArticleDOI
A proof of the data compression theorem of Slepian and Wolf for ergodic sources (Corresp.)
TL;DR: It is established that the Slepian-Wolf theorem is true without change for arbitrary ergodic processes \{(X_i,Y_i)\}_{i=1}^{\infty} and countably infinite alphabets.

On source coding with side information at the decoder
TL;DR: The characterization of the family of rate triples (R_0,R_1, R_2) for which this system can deliver essentially perfect reproductions of X and Y and the principal result is a characterization of this family via an information-theoretic minimization.
