Multichannel audio can immerse a group of listeners in a seamless aural environment. However, several issues must be addressed, such as the excessive transmission requirements of multichannel audio, as well as the fact that to-date only a handful of music recordings have been made with multiple channels. Previously, we proposed a system capable of synthesizing the multiple channels of a virtual...

SystemC AMS extensions introduce new language constructs for the design of embedded analog/mixed-signal systems. This paper presents the novel modeling language for analog and mixed-signal functions that supports design and modeling of telecommunications, automotive and imaging sensor applications at various levels of abstraction. A simple example illustrates how these new features facilitate a...

In this paper we will present advanced 3D signal processing for an extended architecture of ‘Virtual Team User Environments (VIRTUE)’ a recently proposed concept on immersive 3D videoconferencing. Due to certain reasons the current VIRTUE architecture is restricted to a connection between three single user terminals. To overcome these shortcomings, a flexible multi-user concept is currently und...

 This paper describes a remote-experimentation project that is part of a virtual laboratory (VLab). The activity is organized around a spectrum analyzer and a function generator, as real devices mirrored into Web (Internet) nodes. A logically structured replica of the Advantest spectrum analyzer is realized on a LabVIEW platform, in a client-server approach. The application also integrates sev...

There are some paradoxes in the SoC industry. Here is the crux of the matter for the analog and fast electrical parts: Innovative products involving SoC development often require usage of the latest technological process, together with a mix of high performance logic and analog functions. Reducing cost, time and risk of SoC designs requires the re-use of Virtual Components. Well, re-use clearly...

We consider correlation-based imaging of a reflector located on one side of a passive array where the medium is homogeneous. On the other side of the array the illumination by remote impulsive sources goes through a strongly scattering medium. It has been shown in [J. Garnier and G. Papanicolaou, Inverse Problems, 28 (2012), 075002] that migrating the cross correlations of the passive array giv...

In this work, aspects in real-time modeling and synthesis of three-dimensional sound in the context of digital audio, multimedia, and virtual environments are studied. The concept of virtual acoustics is discussed, which includes models for sound sources, room acoustics, and spatial hearing. Real-time virtual acoustics modeling is carried out using a real-time parametric room impulse response r...

Due to the growing computation rates of intensive signal processing applications, using Multiprocessor System on Chip (MPSoC) becomes an incontrovertible solution to meet the functional requirements. Today, Electronic System Level (ESL) design is considered a vital premise to overcome the design complexity intrinsic in the heterogeneity of these devices. However, the development of tools at the...
