  2. 1. Signal Separation - II

    Author : Ulf Lindgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local convergence; mutual information; chi square test; signal enhancement; parameter identifiability; source separation; signal separation; algorithms;

    Abstract : Signal separation is a signal processing technique which enables the separation of superimposed signals. There are several practical situations were signal separation can be used, for example in noise reduction for cellular phones subject to background noise. READ MORE

    Abstract : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. READ MORE

  7. 5. Sound field separation with microphone arrays

    Author : Elias Zea; Ines Lopez Arteaga; Mats Åbom; Leif Kari; Jean-Hugh Thomas; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound field separation; Microphone arrays; Near-field acoustic holography; Reflecting surfaces; Railway rolling noise; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Sound field analysis is a fundamental tool in the design, manufacturing, testing and diagnosis of machines and transportation means, as well as the legislations that regulate noise levels in order to minimize environmental pollution. Customary solutions to the problem of sound field analysis are microphone array technologies such as near-field acoustic holography (NAH) and beamforming. READ MORE
