  1. 1. Suppression of impulsive noise in wireless communication

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :qiaofeng cui; [2014]
    Nyckelord :GPS receiver; fastICA; BPSK; Impulsive Noise; Blind Signal Separation; Independent Component Analysis; ;

    Sammanfattning : This report intends to verify the possibility that the FastICA algorithm could be applied to the GPS system to eliminate the impulsive noise from the receiver end. As the impulsive noise is so unpredictable in its pattern and of great energy level to swallow the signal we need, traditional signal selection methods exhibit no much use in dealing with this problem.

  3. 2. Combining Beamforming and Blind Source Separation to Improve Source Separation Performance

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

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

    Sammanfattning : 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). LÄS MER

  4. 3. Study of ASA Algorithms

    Master-uppsats, Elektroniksystem

    Författare :Nagaraju Ardam; [2010]
    Nyckelord :Auditory Scene Analysis ASA ; Noise suppression; ICA; Blind Source Separation; Hearing-Aid;

    Sammanfattning : Hearing aid devices are used to help people with hearing impairment. The number of people that requires hearingaid devices are possibly constant over the years, however the number of people that now have access to hearing aiddevices increasing rapidly. The hearing aid devices must be small, consume very little power, and be fairly accurate. LÄS MER

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

    Uppsats för yrkesexamina på grundnivå, Institutionen för konstruktions- och produktionsteknik

    Författare :Martin D. Mileros; [2004]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
