  1. 1. Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

    Författare :Svante Björklund; Mats Pettersson; Ingvar Claesson; Ulrich Nickel; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radar; signal processing; array antenna; subarray; clutter; jamming; interference; direction of arrival estimation; security; micro-Doppler; feature extraction; classification;

    Sammanfattning : Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather. LÄS MER

  2. 2. Applications of Soft Computing Techniques for Wireless Communications

    Författare :Maria Erman; Ingvar Claesson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis presents methods and applications of Fuzzy Logic and Rough Sets in the domain of Telecommunications at both the network and physical layers. Specifically, the use of a new class of functions, the truncated π functions, for classifying IP traffic by matching datagram size histograms is explored. LÄS MER

  3. 3. Measurements, Analysis Techniques and Experiments in Sound and Vibration : Applied to Operational MRI Scanners and in Remote Laboratories

    Författare :Imran Khan; Lars Håkansson; Ingvar Claesson; Josef Ström Bartunek; Gustavo R. Alves; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Noise Control; Remote Laboratories; Sound and Vibration Measurements; Vibration Analysis; Vibration Transmission;

    Sammanfattning : High quality noise and vibration measurements outside of a laboratory environment on real life structures and applications are not trivial. True boundary and operating conditions enforce unique challenges on the measurements. Measurements in hazardous situations such as high magnetic fields, and high temperature environments, etc. LÄS MER

  4. 4. Low-Complexity Signal Processing for Speech Enhancement and Audio Analysis

    Författare :Markus Lindroth; Benny Lövström; Ingvar Claesson; Fredric Lindström; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied Signal Processing; Tillämpad signalbehandling;

    Sammanfattning : In real-time signal processing there is a constraint to finish processing of an audio signal before the next audio segment is received. This makes it important to have signal processing algorithms with low computational complexity while still maintaining high quality results. LÄS MER

  5. 5. FINGERPRINT IMAGE ENHANCEMENT, SEGMENTATION AND MINUTIAE DETECTION

    Författare :Josef Ström Bartunek; Ingvar Claesson; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive fingerprint image enhancement; fingerprint segmentation; gray-scale image normalization; minutiae features; neural networks; frequency analysis; kurtosis;

    Sammanfattning : Prior to 1960's, the fingerprint analysis was carried out manually by human experts and for forensic purposes only. Automated fingerprint identification systems (AFIS) have been developed during the last 50 years. The success of AFIS resulted in that its use expanded beyond forensic applications and became common also in civilian applications. LÄS MER
