  1. 16. Blind Signal Separation by Second Order Statistics

    Författare :Henrik Sahlin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The problem of separating uncorrelated signals from equally many observed mixtures is considered in this thesis. Each observed signal is modeled as a sum of original signals filtered through unknown linear filters. LÄS MER

  3. 17. 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

  4. 18. Digitally controlled analog multiply-accumulate units

    Författare :Mattias Duppils; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is about digitally controlled analog multiplier-accumulator (MAC) units and their utilization in communications applications. These units are implemented as switched-capacitor circuits, designed with switches (MOS transistors), capacitors (MOS transistors), and amplifiers (MOS transistors); using a CMOS technology. LÄS MER

  5. 19. Robust broadband beamforming and digital filter design : methods and applications

    Författare :Sven Nordebo; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This doctoral thesis consists of a summary and six parts corresponding to six different papers. There are two published and three submitted journal papers, and one research report. The summary will highlight the main results and emphasize the interrelationships between different parts. LÄS MER

  7. 20. Pipeline Analog-Digital Converters Dynamic Error Modeling for Calibration : Integral Nonlinearity Modeling, Pipeline ADC Calibration, Wireless Channel K-Factor Estimation

    Författare :Samer Medawar; Peter Händel; Niclas Björsell; Magnus Jansson; Dominique Dallet; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analog-digital converter; integral nonlinearity; calbiration; K-factor estimation;

    Sammanfattning : This thesis deals with the characterization, modeling and calibration of pipeline analog-digital converters (ADC)s. The integral nonlinearity (INL) is characterized, modeled and the model is used to design a post-correction block in order to compensate the imperfections of the ADC. LÄS MER
