Capacity Bounds for the Gaussian Interference Channel
Abstract-- The capacity region of the two-user Gaussian Interference Channel (IC) is studied. Two classes of channels are considered: weak and mixed Gaussian IC. For the weak Gauss...

Fast likelihood computation using hierarchical Gaussian shortlists
We investigate the use of hierarchical Gaussian shortlists to speed up Gaussian likelihood computation. This approach is a combination of hierarchical Gaussian selection and stand...

A Scale-Space Approach for Image Registration of Vessel Structures
Abstract. We present a multi-scale approach for non-rigid image registration of tubular tree-like structures such as vessels. Therefore, we consider a Gaussian and a combined morph...

On the Calculation of OFDM Error Performance with Phase Noise in AWGN and Fading Channels
Oscillator phase noise (PN) in orthogonal frequency division multiplexing (OFDM) systems can cause severe performance degradation. In contrary to the assumptions made previously, r...

A Simple IR-UWB Receiver Adapted to Multi-User Interferences
— We propose in this paper a simple receiver adapted to Multi User Interferences (MUI) in Impulse Radio Ultra Wide Band (IR-UWB). It is known that MUI distribution is not Gaussia...

Gait Learning-Based Regenerative Model: A Level Set Approach
We propose a learning method for gait synthesis from a sequence of shapes(frames) with the ability to extrapolate to novel data. It involves the application of PCA, first to redu...
