1. 1. Blind Acoustic Feedback Cancellation for an AUV

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Hampus Frick; [2023]
   Nyckelord :acoustical feedback; adaptive filter; least leaky mean square; Kalman; blind source separation; independent component analysis; complex independent component analysis; degenerative unmixing estimation technique; convolutive mixture;

   Sammanfattning : SAAB has developed an autonomous underwater vehicle that can mimic a conventional submarine for military fleets to exercise anti-submarine warfare. The AUV actively emits amplified versions of received sonar pulses to create the illusion of being a larger object. LÄS MER

3. 2. Speech Intelligibility in Radio Broadcasts : A Case Study Using Dynamic Range Control and Blind Source Separation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Martin Linder Nilsson; [2022]
   Nyckelord :Speech enhancement; speech intelligibility; audibility; dynamic range control; blind source separation; object-based audio; public service.;

   Sammanfattning : Creating the optimal balance between dialogue level and ambient sound is extremely important in media productions. This process is however inherently difficult due to that people’s requirements and preferences are not uniform. LÄS MER

4. 3. Venous Component Separation From a Pulse Oximeter Signal using Blind Source Separation with Ultrasound Imaging as Reference

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Björn Walter; Stefan Piiroinen; [2021]
   Nyckelord :Photoplethysmogram; PPG; Ultrasound; Blind Source Separation; PCA; SOBI; venous component; Technology and Engineering;

   Sammanfattning : Intradialytic hypotension (IDH) is a major drawback of haemodialysis and occurs in more than every fifth dialysis treatment. There is a need for real-time measurement, with an ability to detect IDH before it occurs. Photoplethysmography (PPG) may provide sufficient information about hemodynamic status to prevent IDH.

5. 4. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Luke Postema; Johan Davidsson; [2019]
   Nyckelord :Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

   Sammanfattning : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. LÄS MER

7. 5. 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.
