  4. 3. On the Implementation of Integer and Non-Integer Sampling Rate Conversion

    Författare :Muhammad Abbas; Håkan Johansson; Oscar Gustafsson; Vassilis Paliouras; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The main focus in this thesis is on the aspects related to the implementation of integer and non-integer sampling rate conversion (SRC). SRC is used in many communication and signal processing applications where two signals or systems having different sampling rates need to be interconnected. LÄS MER

  5. 4. GNSS-aided INS for land vehicle positioning and navigation

    Författare :Isaac Skog; Peter Händel; Bengt Boberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER
