Vector perturbation precoding for receivers with limited dynamic range
In this paper we consider the vector perturbation (VP) precoding scheme for the multiuser MISO broadcast channel proposed by Hochwald et al. under the practical assumption that th...

Modeling of contours in wavelet domain for generalized lifting image compression
This paper introduces the design of context-based models of contours in the wavelet domain, which are used to construct generalized lifting (GL) mappings for image compression. Th...

Control of prosodic focus in corpus-based generation of fundamental frequency contours of Japanese based on the generation proce
A total corpus-based process of generating prosodic features from text is developed. The process first predicts pauses and phone durations, and then generates F0 contours. Since F...
