event driven data acquisition and continuous time Digital Signal processing
Custom Integrated Circuits Conference, 2010Co-Authors: Yannis TsividisAbstract:This paper reviews research in event-driven data acquisition and associated Digital Signal processing. The approaches considered can potentially offer significant energy and bandwidth savings with certain important classes of Signals, in which activity varies significantly with time. An extensive bibliography is provided.

event driven data acquisition and Digital Signal processing a tutorial
IEEE Transactions on Circuits and Systems Ii-express Briefs, 2010Co-Authors: Yannis TsividisAbstract:Event-driven analog-to-Digital conversion and associated Digital Signal processing techniques are reviewed. Such techniques, still in the research stage, have the potential to significantly reduce the consumption of energy and bandwidth resources in several important applications.

Signal dependent variable resolution quantization for continuous time Digital Signal processing
International Symposium on Circuits and Systems, 2009Co-Authors: Mariya Kurchuk, Yannis TsividisAbstract:A variable-bit quantization scheme is proposed for use in the context of continuous-time Digital Signal processing, with resolution depended on Signal speed. It is shown that a decrease in resolution for fast inputs does not corrupt the inband spectrum, while leading to power savings. Analysis and extensive simulations are provided.

experimental demonstration of a format flexible single carrier coherent receiver using data aided Digital Signal processing
Optics Express, 2012Co-Authors: Robert Elschner, Felix Frey, C Meuer, Johannes Karl Fischer, Saleem Alreesh, C Schmidtlanghorst, L Molle, Takahito Tanimura, C SchubertAbstract:We experimentally demonstrate the use of data-aided Digital Signal processing for format-flexible coherent reception of different 28-GBd PDM and 4D modulated Signals in WDM transmission experiments over up to 7680 km SSMF by using the same resource-efficient Digital Signal processing algorithms for the equalization of all formats. Stable and regular performance in the nonlinear transmission regime is confirmed.

active sound and vibration control using adaptive Digital Signal processing
International Conference on Acoustics Speech and Signal Processing, 1993Co-Authors: L J ErikssonAbstract:Active sound and vibration control is a rapidly emerging technology that has application to a wide variety of problems in manufacturing. These include reducing the exposure of workers to undesired noise and vibration, improving the quality of the product being produced, and allowing increased production rates for various processes and operations. Although the basic idea is quite old, the concept has not been practical until recently due to the development of powerful, low-cost Digital Signal processing systems. In addition, a variety of new adaptive filter techniques has broadened the range of applications. Adaptive Digital Signal processing enables the desired model to be determined in an online fashion using a system identification framework. The residual sound or vibration may be used as an error Signal in an adaptive filter structure such as the least mean squares (LMS) algorithm to determine adaptively the correct model. >

dspsr Digital Signal processing software for pulsar astronomy
Publications of the Astronomical Society of Australia, 2011Co-Authors: W Van Straten, M BailesAbstract:dspsr is a high-performance, open-source, object-oriented, Digital Signal processing software library and application suite for use in radio pulsar astronomy. Written primarily in C++, the library implements an extensive range of modular algorithms that can optionally exploit both multiple-core processors and general-purpose graphics processing units. After over a decade of research and development, dspsr is now stable and in widespread use in the community. This paper presents a detailed description of its functionality, justification of major design decisions, analysis of phase-coherent dispersion removal algorithms, and demonstration of performance on some contemporary microprocessor architectures.
