We address covariance estimation under mean-squared loss in the Gaussian setting. Specifically, we consider shrinkage methods which are suitable for high dimensional problems wit...
In this paper we present an alternative separable implementation of L2 -orthogonal space-time codes (STC) for continuous phase modulation (CPM). In this approach, we split the STC...
—We are now living in a world where information is growing and updating quickly. Knowledge can be acquired more efficiently with the help of automatic document summarization and...
—The majority of security protocols employ public key cryptography for authentication at least in the connection setup phase. However, verifying digital signatures is an expensiv...
—We study the dissemination of dynamic content, such as news or traffic information, over a mobile social network. In this application, mobile users subscribe to a dynamic-conte...
