On Gaussian MIMO compound wiretap channels
— We study the two-user one-eavesdropper discrete memoryless compound wiretap channel, where the transmitter sends a common confidential message to both users, which needs to be...

Gaussian Interference Channel Capacity to Within One Bit
—The capacity of the two-user Gaussian interference channel has been open for 30 years. The understanding on this problem has been limited. The best known achievable region is du...

A Self-healing Key Distribution Scheme with Novel Properties
We improve a secret sharing scheme, which enables users select their personal keys by themselves instead of being distributed by group manager and users can reuse their personal k...

Channel Orthogonalizing Precoder for Open-Loop QO-STBC Systems
—This paper proposes a new preprocessing scheme for rate-one quasi-orthogonal space-time block code (QO-STBC), which requires no channel state information at the transmitter. We ...

How Good is Opportunistic Routing? - A Reality Check under Rayleigh Fading Channels
Considerations of realistic channel dynamics motivate the design of a new breed of opportunistic schemes, such as opportunistic transmission, scheduling and routing. Compared to t...
