On the h-index, the size of the Hirsch core and Jin's A-index
Hirsch’s h-index seeks to give a single number that in some sense summarizes an author’s research output and its impact. Essentially, the h-index seeks to identify the most pr...

A Theory for Sampling Signals From a Union of Subspaces
One of the fundamental assumptions in traditional sampling theorems is that the signals to be sampled come from a single vector space (e.g. bandlimited functions). However, in many...

Guaranteeing Practical Convergence in Algorithms for Sensor and Source Localization
This paper considers localization of a source or a sensor from distance measurements. We argue that linear algorithms proposed for this purpose are susceptible to poor noise perfor...

Generalized Design of Multi-User MIMO Precoding Matrices
In this paper we introduce a novel linear precoding technique. The approach used for the design of the precoding matrix is general and the resulting algorithm can address several o...
