Cooperative Secret Communication with Artificial Noise in Symmetric Interference Channel
We consider the symmetric Gaussian interference channel where two users try to enhance their secrecy rates in a cooperative manner. Artificial noise is introduced along with useful...

Joint Source Channel Coding with Side Information Using Hybrid Digital Analog Codes
We study the joint source channel coding problem of transmitting an analog source over a Gaussian channel in two cases - (i) the presence of interference known only to the transmit...

High-dimensional subset recovery in noise: Sparsified measurements without loss of statistical efficiency
We consider the problem of estimating the support of a vector Rp based on observations contaminated by noise. A significant body of work has studied behavior of 1-relaxations when...
