    • High Resolution MRI of Spinal Cords 

      Yu, Xiangdong; Li, Peng (2014-09-02)
      Spinal Cord Injury (SCI) is a common injury in incorrect sitting position, sports and car accidents. Noninvasive imaging methods play a critical role in diagnosing SCI and monitoring the response to therapy. Magnetic ...
    • Image Reconstructions of Compressed Sensing MRI with Multichannel Data 

      Chang, Ching-Hua (2016-05-06)
      Magnetic resonance imaging (MRI) provides high spatial resolution, high-quality of soft-tissue contrast, and multi-dimensional images. However, the speed of data acquisition limits potential applications. Compressed sensing ...
    • LDPC Codes over Large Alphabets and Their Applications to Compressed Sensing and Flash Memory 

      Zhang, Fan (2010-10-12)
      This dissertation is mainly focused on the analysis, design and optimization of Low-density parity-check (LDPC) codes over channels with large alphabet sets and the applications on compressed sensing (CS) and flash memories. ...
    • Robustness of Compressed Sensing in Sensor Networks 

      Hern, Brett (2008-05-22)
      Compressed sensing is a new theory that is based on the fact that many natural images can be sparsely represented in an orthonormal wavelet basis. This theory holds valuable implications for wireless sensor networks ...
    • Spectral Estimation for Graph Signals Using Reed-Solomon Decoding 

      Deb, Abhishek (2017-07-21)
      Spectral estimation, coding theory and compressed sensing are three important sub-fields of signal processing and information theory. Although these fields developed fairly independently, several important connections ...
