  • Lattice Algorithms for Compression Color Space Estimation in JPEG Images 

    Neelamani, Ramesh; de Queiroz, Ricardo; Baraniuk, Richard G. (2001-08-01)
    JPEG (Joint Photographic Experts Group) is an international standard to compress and store digital color images [5]. Given a color image that was previously JPEG-compressed in some hidden color space, we aim to estimate ...
  • Layered Dynamic Fault Detection and Tolerance for Robots 

    Visinsky, Monica L.; Walker, Ian D.; Cavallaro, Joseph R. (1993-05-01)
    Fault tolerance is increasingly important for space and hazardous environment robotics. Robots need to quickly detect and tolerate internal failures in order to continue performing their tasks without the need for immediate ...
  • LDPC Code Design for Half-Duplex Decode-and-Forward Relaying 

    Chakrabarti, Arnab; de Baynast, Alexandre; Sabharwal, Ashutosh; Aazhang, Behnaam (2005-09-01)
    We propose LDPC code designs for the half-duplex relay channel. Our designs mimic the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it is built ...
  • LDPC Code Design for OFDM Channel: Graph Connectivity and Information Bits Positioning 

    de Baynast, Alexandre; Sabharwal, Ashutosh; Aazhang, Behnaam (2005-07-01)
    We present an optimized channel coding scheme for OFDM transmission. In the future wireless standards such IEEE 802.11n, frame error rates (FER) as low as 0.0001 are targeting. Irregular LDPC codes have excellent performance ...
  • LDPC Code Design for Relay Channel in Time-Division mode 

    de Baynast, Alexandre; Chakrabarti, Arnab; Sabharwal, Ashutosh; Aazhang, Behnaam (2006-06-01)
    We address the problem of LDPC code design for relay channel in time-division mode based on a distributed strategy: In the first time slot, the source transmits part of the codeword. The relay and the destination receive ...
  • LDPC Code-Design for the Relay Channel 

    Chakrabarti, Arnab; de Baynast, Alexandre; Sabharwal, Ashutosh; Aazhang, Behnaam (2006-02-01)
    We propose LDPC code designs for the half-duplex relay channel. Our designs are derived from the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it ...

  • Learning minimum volume sets with support vector machines 

    Davenport, Mark A.; Baraniuk, Richard G.; Scott, Clayton D. (2006-09-01)
    Given a probability law P on d-dimensional Euclidean space, the minimum volume set (MV-set) with mass beta , 0 < beta < 1, is the set with smallest volume enclosing a probability mass of at least beta. We examine the use ...
  • Lifting Construction of Non-Linear Wavelet Transforms 

    Claypoole, Roger L.; Baraniuk, Richard G.; Nowak, Robert David (1998-10-01)
    This paper analyzes non-linear wavelet transforms using the lifting construction. The lifting construction exploits a spatial-domain, prediction-error interpretation of the wavelet transform and provides a powerful framework ...
  • A Limitation of the Kernel Method for Joint Distributions of Arbitrary Variables 

    Baraniuk, Richard G. (1996-02-01)
    Recently, Cohen has proposed a construction for joint distributions of arbitrary physical quantities, in direct generalization of joint time-frequency representations. Actually this method encompasses two approaches, one ...
  • The Limiting Density of a Nonlinear System 

    Papantoni-Kazakos, P.; Kazakos, D. (1974-10-20)
    The RC filter-hard limiter-RC filter nonlinear system shown in Fig. 1 is the subject of this paper. Because of computational difficulties implicated in the analysis of the above system, only its response to the zero mean ...
  • Limits of population coding 

    Johnson, Don (2003-07-20)
    To understand whether the population response expresses information better than the aggregate of the individual responses, the sum of the individual contributions is frequently used as a baseline against which to assess ...
  • Linear finite memory-length multiuser detectors 

    Juntti, Markku J.; Aazhang, Behnaam (1995-10-20)
    Decorrelating, LMMSE, and the noise-whitening multiuser detectors for code division multiple access (CDMA) are ideally infinite memory length (IIR) detectors. To obtain more practical and robust systems linear finite ...

    de Figueiredo, Rui J.P. (1975-07-20)
    As an extension of the notion of an <em>L-g</em> spline, three mathematical structures called <em>LM-g</em> splines of types, I, II and II are introduced. (partial abstract)

    Ribeiro, Vinay Joseph; Riedi, Rudolf H.; Baraniuk, Richard G. (2004-09-01)
    The Spatio-temporal Available Bandwidth estimator (STAB), a new edge-based probing tool, locates thin links --- those links with less available bandwidth than all links preceeding them --- on end-to-end network paths. By ...
