An optimal filtering algorithm for non-parametric observation models in robot localization
— The lack of a parameterized observation model in robot localization using occupancy grids requires the application of sampling-based methods, or particle filters. This work ad...

Performance of a Structured IRA Code on a Perpendicular Recording Channel with Media Noise
Abstract—We examine the performance of a rate-0.9 structured irregular repeat-accumulate (S-IRA) code on a perpendicular magnetic recording (PMR) channel with media noise. To acc...

Generalized CRLB for DA and NDA Synchronization of UWB Signals with Clock Offset
—In this paper the Cramér-Rao lower bound (CRLB) of an ultra-wideband (UWB) pulse amplitude modulated (PAM) signal with time hopping (TH) code is derived for the practical case ...
