On expectation maximization based channel and noise estimation beyond the vector Taylor series expansion
In this work, we show how expectation maximization based simultaneous channel and noise estimation can be derived without a vector Taylor series expansion. The central idea is to ...

Capacity-Equivocation Region of the Gaussian MIMO Wiretap Channel
We study the Gaussian multiple-input multiple-output (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the transmit...

On the inner and outer bounds for 2-receiver discrete memoryless broadcast channels
We study the best known general inner bound[1] and outer bound[2] for the capacity region of the two user discrete memory less channel. We prove that a seemingly stronger outer bou...

Robust Matrix Decomposition with Outliers
Suppose a given observation matrix can be decomposed as the sum of a low-rank matrix and a sparse matrix (outliers), and the goal is to recover these individual components from th...
