Multiple-Input Multiple-Output Gaussian Broadcast Channels with Common and Confidential Messages
Hung D. Ly, Tie Liu, Yingbin Liang
This paper considers the problem of the multiple-input multiple-output (MIMO) Gaussian broadcast channel with two receivers (receivers 1 and 2) and two messages: a common message i…
Multiple-Input Multiple-Output Gaussian Broadcast Channels with Confidential Messages
Ruoheng Liu, Tie Liu, H. Vincent Poor +1
This paper considers the problem of secret communication over a two-receiver multiple-input multiple-output (MIMO) Gaussian broadcast channel. The transmitter has two independent m…
A Vector Generalization of Costa's Entropy-Power Inequality with Applications
Ruoheng Liu, Tie Liu, H. Vincent Poor +1
This paper considers an entropy-power inequality (EPI) of Costa and presents a natural vector generalization with a real positive semidefinite matrix parameter. This new inequality…
Transmission Capacities for Overlaid Wireless Ad Hoc Networks with Outage Constraints
Changchuan Yin, Long Gao, Tie Liu +1
We study the transmission capacities of two coexisting wireless networks (a primary network vs. a secondary network) that operate in the same geographic region and share the same s…
