Diversity-multiplexing tradeoff in multiple-access channels
TLDR
In a point-to-point wireless fading channel, multiple transmit and receive antennas can be used to improve the reliability of reception (diversity gain) or increase the rate of communication for a fixed reliability level (multiplexing gain). Expand

Sum capacity of the vector Gaussian broadcast channel and uplink-downlink duality
TLDR
We characterize the sum capacity of the vector Gaussian broadcast channel by showing that the existing inner bound of Marton and the existing upper bound of Sato are tight for this channel. Expand

Optimal sequences, power control, and user capacity of synchronous CDMA systems with linear MMSE multiuser receivers
TLDR
We characterize the user capacity of a single cell with the optimal linear receiver (MMSE receiver). Expand

Optimal sequences and sum capacity of synchronous CDMA systems
TLDR
The sum capacity of a multiuser synchronous CDMA system is completely characterized in the general case of asymmetric user power constraints-this solves the open problem posed by Rupf and Massey. Expand

Extremal Mechanisms for Local Differential Privacy
TLDR
We introduce a family of extremal privatization mechanisms, which we call staircase mechanisms, and prove that it contains the optimal privatization mechanism that maximizes utility. Expand

The Composition Theorem for Differential Privacy
TLDR
We answer the fundamental question of characterizing the level of overall privacy degradation as a function of number of queries and the privacy levels maintained by each privatization mechanism. Expand
