  2. 1. Techniques for Efficient Implementation of FIR and Particle Filtering

    Author : Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

    Abstract : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters.

  4. 2. All Digital Polar Transmitter Design for Software Defined Radio : Architecture and Low Power Circuit Implementation

    Author : Liang Rong; Li-Rong Zheng; Henrik Sjöland; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Switching Power Amplifier; All Digital Polar Transmitter; Lowpass Sigma Delta Modulation; Software Defined Radio; RFID; H-Bridge Architecture; Resonating; Filter Matching Network.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : The evolving wireless communication technology is aiming highdata rate, high mobility, long distance and at the meantime, co-existwith various different standards. This developing trend requires ahighly linear transceiver system and it causes the problem of lowefficiency due to the large crest factor of signals. READ MORE

  5. 3. Filtering extracting features from infrasound data

    Author : José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; magnetometer; Physics; Fysik; Electronics;

    Abstract : The goal of the research presented in this thesis is to extract features, to filter and get fingerprints from signals detected by infrasound, seismic and magnetic sensors. If this can be achieved in a real time system, then signals from various events can be detected and identified in an otherwise torrent data. READ MORE

  6. 4. Feature Extraction for Low-Frequency Signal Classification

    Author : José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

    Abstract : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. READ MORE
