  1. 1. Combining Beamforming and Blind Source Separation to Improve Source Separation Performance

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Written: Aishwarya Sivaramakrishnan; Ruben Johnson Robert Jeremiah; [2013]
    Keywords : Blind Source Separation; Beamforming; Combining Technique; ICA; Frequency Domain BSS;

    Abstract : Beamforming (BF) and Blind Source Separation (BSS) are always two interesting methodologies to witness in order to separate two sources. BSS in frequency domain have been facing a serious issue of permutation ambiguity while performing source separation using Independent Component Analysis (ICA). READ MORE

  3. 2. BLIND SOURCE SEPARATION USING FREQUENCY DOMAIN INDEPENDENT COMPONENT ANALYSIS

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Okwelume Gozie E.; Ezeude Anayo Kingsley; [2007]
    Keywords : Independent Component Analysis; Blind Source Seperation; Fourier Transform; Short Time Fourier Transform;

    Abstract : Our thesis work focuses on Frequency-domain Blind Source Separation (BSS) in which the received mixed signals are converted into the frequency domain and Independent Component Analysis (ICA) is applied to instantaneous mixtures at each frequency bin. Computational complexity is also reduced by using this method. READ MORE

  4. 3. Real-Time Implementation of a Combined PCA-ICA Algorithm for Blind Source Separation

    University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

    Author : Magnus Berg; Erik Bondesson; [2005]
    Keywords : PCA; ICA; BSS; Permutation; DOA; Kurtosis;

    Abstract : In this thesis we introduce and investigate a method combining Principle Component Analysis (PCA) and Independent Component Analysis (ICA) for Blind Source Separation (BSS). A recursive method for the PCA is applied to meet the demands of a real-time application, and for the ICA algorithm, the Information maximization principle is used. READ MORE

  5. 4. A Real-Time Classification approach of a Human Brain-Computer Interface based on Movement Related Electroencephalogram

    University essay from Institutionen för konstruktions- och produktionsteknik

    Author : Martin D. Mileros; [2004]
    Keywords : Technology; Real-Time Brain-Computer Interface RT-BCI ; Blind Signal Separation BSS ; Canonical Correlation Analysis CCA ; Electroencephalogram EEG ; Artificial Neural Networks ANN ; Real-Time Classification RTC ; Ten-Twenty Electrode Application System 10-20 System ; TEKNIKVETENSKAP;

    Abstract : A Real-Time Brain-Computer Interface is a technical system classifying increased or decreased brain activity in Real-Time between different body movements, actions performed by a person. Focus in this thesis will be on testing algorithms and settings, finding the initial time interval and how increased activity in the brain can be distinguished and satisfyingly classified. READ MORE
