Light-cone quantization of scalar field on time-dependent backgrounds

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We discuss what is light-cone quantization on a curved spacetime also without a null Killing vector. Then we consider as an example the light-cone quantization of a scalar field on a background with a Killing vector and the connection with the second ...

Adaptive multistage vector quantization [PDF]

open access: yesProceedings. Electrotechnical Conference Integrating Research, Industry and Education in Energy and Communication Engineering', 2003
The authors present a novel multiple-stage vector-quantization method that allows the adaptation of the quantizer to the signal to be coded. This adaptation is computationally very simple and is made with no increase in bit rate. The resulting quantizer provides a robust performance across different speakers and environments. It has been applied to the

Results on lattice vector quantization with dithering [PDF]

open access: yes, 1996
The statistical properties of the error in uniform scalar quantization have been analyzed by a number of authors in the past, and is a well-understood topic today. The analysis has also been extended to the case of dithered quantizers, and the advantages
