  1. 1. Compressed Sensing Algorithms and Applications

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dennis Sundman; KTH.; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressed sensing; greedy pursuits; subspace pursuit; orthogonal matching pursuit; power spectral density estimation; distributed compressed sensing;

    Abstract : The theoretical problem of finding the solution to an underdeterminedset of linear equations has for several years attracted considerable attentionin the literature. This problem has many practical applications.One example of such an application is compressed sensing (cs), whichhas the potential to revolutionize how we acquire and process signals. READ MORE

  2. 2. Source and Channel Coding for Compressed Sensing and Control

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Amirpasha Shirazinia; KTH.; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Source coding; quantization; channel coding; compressed sensing; control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Rapid advances in sensor technologies have fueled massive torrents of data streaming across networks. Such large volume of information, indeed, restricts the operational performance of data processing, causing inefficiency in sensing, computation, communication and control. READ MORE

  3. 3. Greedy Algorithms for Distributed Compressed Sensing

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dennis Sundman; KTH.; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Compressed sensing (CS) is a recently invented sub-sampling technique that utilizes sparsity in full signals. Most natural signals possess this sparsity property. From a sub-sampled vector, some CS reconstruction algorithm is used to recover the full signal. READ MORE

  4. 4. Sparse representation of visual data for compression and compressed sensing

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Ehsan Miandji; Linköpings universitet.; Linköpings universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The ongoing advances in computational photography have introduced a range of new imaging techniques for capturing multidimensional visual data such as light fields, BRDFs, BTFs, and more. A key challenge inherent to such imaging techniques is the large amount of high dimensional visual data that is produced, often requiring GBs, or even TBs, of storage. READ MORE

  5. 5. Sub-Nyquist Sampling Impulse Radio UWB Receivers for the Internet-of-Things

    University dissertation from Stockholm : KTH Royal Institute of Technology
