A network information theory for wireless communication: scaling laws and optimal operation
Liang-Liang Xie,P. R. Kumar +1 more
TL;DR: A model of wireless networks that particularly takes into account the distances between nodes, and the resulting attenuation of radio signals, is formulated, and a performance measure that weights information by the distance over which it is transported is studied.
Journal ArticleDOI
An achievable rate for the multiple-level relay channel
Liang-Liang Xie,P. R. Kumar +1 more
TL;DR: For the multiple-level relay channel, an achievable rate formula, and a simple coding scheme to achieve it, are presented and this achievable rate is shown to be the exact capacity.
Journal ArticleDOI
The transport capacity of wireless networks over fading channels
TL;DR: The thrust of these results is that the multihop strategy, toward which much protocol development activity is currently targeted, is appropriate for fading environments.
Journal ArticleDOI
How much uncertainty can be dealt with by feedback
Liang-Liang Xie,Lei Guo +1 more
TL;DR: In the space of unknown nonlinear functions, the generalized Lipschitz norm is a suitable measure for characterizing the size of the structure uncertainty, and that the maximum uncertainty that can be dealt with by the feedback mechanism is described by a ball with radius 3/2+/spl radic/2 in this normed function space.
Proceedings ArticleDOI
Network Coding and Random Binning for Multi-User Channels
TL;DR: A two-way relay channel and a three-way broadcast channel are considered in this paper, and the corresponding achievable rate regions are determined.
