Potentials of Opportunistic Routing in Energy-Constrained Wireless Sensor Networks
Martin Vetterli, François Ingelrest
The low quality of wireless links leads to perpetual packet losses. While an acknowledgment mechanism is generally used to cope with these losses, multiple retransmissions nevertheless occur. Opportunistic routing limits these retransmissions by taking adv ...
Springer Berlin / Heidelberg2009Entropy coding of Quantized Spectral Components in FDLP audio codec
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy
Audio codec based on Frequency Domain Linear Prediction (FDLP) exploits auto-regressive modeling to approximate instantaneous energy in critical frequency sub-bands of relatively long input segments. Current version of the FDLP codec operating at 66 kbps h ...
Idiap2008Distributed signal processing for binaural hearing aids
Over the last centuries, hearing aids have evolved from crude and bulky horn-shaped instruments to lightweight and almost invisible digital signal processing devices. While most of the research has focused on the design of monaural apparatus, the use of a ...
EPFL2008Temporal Masking for Bit-rate Reduction in Audio Codec Based on Frequency Domain Linear Prediction
Petr Motlicek, Hynek Hermansky, Sriram Ganapathy
Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive model to approximate Hilbert envelopes in frequency sub-bands for relatively long temporal segments. Although the basic technique achieves good quality of the reconstructe ...
2008Efficient Data Flow Variable Length Decoding Implementation for the MPEG Reconfigurable Video Coding Framework
Marco Mattavelli, Christophe Lucarz, Stephan Keller
In 2004, ISO/IEC SC29 better known as MPEG started a new standard initiative aiming at facilitating the deployment of multi-format video codec design and to enable the possibility of reconfiguring video codecs using a library of standard components. The ne ...
