  2. 1. Signal Processing Techniques in Mobile Communication Systems : Signal Separation, Channel Estimation and Equalization

    Author : Ronnie Landqvist; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless mobile communications; signal processing; blind source separation; independent component analysis; beamforming; water filling; greedy algorithm; exact eigendecomposition; eigenvector algorithm; multiple-input multiple-output systems; the projection approximation subspace tracking algorithm with and without deflation; linear and non-linear principal component analysis; whitening; decorrelation; equalization; antenna arrays;

    Abstract : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. READ MORE

  4. 2. Model-based and matched-filterbank signal analysis

    Author : Andreas Jakobsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-parametric spectral estimation; efficient implementations; array processing; parameter estimation; identifiability; subspace fitting; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

    Abstract : The dissertation deals with model-based and matched-filterbank signal analysis. The matched-filterbank (MAFI) spectral estimation approach is introduced, and it is shown that both the amplitude spectrum Capon (ASC) and the amplitude and phase estimation (APES) spectral estimators can be expressed as MAFI spectral estimators.

  5. 3. Reduction of Substrate Noise in Mixed-Signal Circuits

    Author : Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

    Abstract : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. READ MORE

  6. 4. Low-Voltage Analog-to-Digital Converters and Mixed-Signal Interfaces

    Author : Prakash Harikumar; Jacob Wikner; Atila Alvandpour; Dag T. Wisland; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Analog-to-digital converters (ADCs) are crucial blocks which form the interface between the physical world and the digital domain. ADCs are indispensable in numerous applications such as wireless sensor networks (WSNs), wireless/wireline communication receivers and data acquisition systems. READ MORE
