  1. 1. Parameter Estimation for Multisensor Signal Processing Reduced Rank Regression, Array Processing and MIMO Communications

    University dissertation from Stockholm : KTH

    Author : Karl Werner; Sergiy Vorobyov; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Abstract : This thesis deals with three estimation problems motivated by spatial signal processing using arrays of sensors. All three problems are approached using tools from estimation theory, including asymptotical analysis of performance and Cramér-Rao lower bound; Monte Carlo methods are used to evaluate small sample performance.

  2. 2. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter Estimation; Array Signal Processing; STAP; SAR; Ground Penetrating Radar; System Identification; Bilinear Models; Covariance Matrix Estimation; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling; Signal Processing; Signalbehandling;

    Abstract : This thesis is concerned with parameter estimation, signal processing, and applications.In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.

  3. 3. Signal processing applied to acoustic distance estimation and sound classification

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lennart Olsson; [1993]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : The thesis treats some signal processing applications to retrieval of information from acoustic measurements. In the distance estimation applications (parts AI, A2, B and C) an acoustic signal propagates through a physical system and is modified according to some system parameter. READ MORE
