Blind phase recovery in QAM communication systems using characteristic function
In this paper, we present a novel non-data aided method for phase recovery in both square and cross quadrature amplitude modulation (QAM) communication systems, based on character...

Difference image extrapolation for spectral completion in inter-sequence error concealment
Mobile reception of digital TV often suffers from lost blocks and slices due to suboptimal channels. Inter-sequence error concealment reconstructs lost image blocks of distorted h...

Robust speech representation of voiced sounds based on synchrony determination with PLLs
We propose to include synchrony effects, known to exist in the auditory system, to represent voiced parts of the speech signal in a robust way. The system decomposes the input sig...
