Diversity and multiplexing: a fundamental tradeoff in multiple-antenna channels
TLDR
Multiple antennas can be used for increasing the amount of diversity or the number of degrees of freedom in wireless communication systems, but there is a fundamental tradeoff between how much of each any coding scheme can get. Expand

TLDR
We show that the existing outer bounds can be arbitrarily loose in some parameter ranges, and by deriving new outer bounds, we show that a very simple and explicit Han-Kobayashi type scheme can achieve to within a single bit per second per hertz (bit/s/Hz) of the capacity for all values of the channel parameters.

Wireless Network Information Flow: A Deterministic Approach
In a wireless network with a single source and a single destination and an arbitrary number of relay nodes, what is the maximum rate of information flow achievable? We make progress on this longExpand

Linear Multiuser Receivers: Effective Interference, Effective Bandwidth and User Capacity
TLDR
We show that in a large system with each user using random spreading sequences, the limiting interference effects under several linear multiuser receivers can be decoupled, such that each interferer can be ascribed a level of effective interference that it provides to the user to be demodulated.
