Echo suppression is a vital part of every communications system. The use of hands-free communication in cars, computer applications and video conferencing have created further demands for high-quality acoustic echo cancellation. In these applications the acoustic channel has, typically, a long impulse response in the order of 100ms. Typical lengths of adaptive FIR-filters are 500-1500 taps, ass...

This report shows how a string of linear code may be converted into a data ow graph (DFG), then to an event ow graph (EFG), and nally into a temporal speciication (TS).

Fifth International Congress on Sound and Vibration December 15-18, 1997 Adelaide, South Australia Genetic Algorithms for Active Vibration Control

This paper presents an investigation into the development of an active vibration control (AVC) system using genetic algorithms (GAs). During the last two decades, a substantial amount of research work has been carried out using GAs in various disciplines. Although GAs have gained popularity as parallel, global search techniques, their use in the area of active control is limited. This investiga...
