Nonparametric Obstruction Detection for UWB Localization
Ultra-wide bandwidth (UWB) transmission is a promising technology for indoor localization due to its fine delay resolution and obstacle-penetration capabilities. However, the prese...

On the recovery of nonnegative sparse vectors from sparse measurements inspired by expanders
This paper studies compressed sensing for the recovery of non-negative sparse vectors from a smaller number of measurements than the ambient dimension of the unknown vector. We fo...

A hybrid FEC-ARQ protocol for low-delay lossless sequential data streaming
Interactive Internet Applications that rely on sequential streams for lossless data exchange often use retransmission protocols (e.g. TCP) for reliability and the guarantee of seq...
