    An Improved Bound on the List Error Probability and List Distance Properties
    Download  genie.eit.lth.se
    A new upper bound on the list error probability is presented. This bound is derived by combining the techniques for obtaining the tangential union bound with an improved bound on t...

    An Improved Sphere-Packing Bound for Finite-Length Codes Over Symmetric Memoryless Channels
    Download  webee.technion.ac.il
    This paper derives an improved sphere-packing (ISP) bound for finite-length error-correcting codes whose transmission takes place over symmetric memoryless channels, and the codes...

    Parameter choices and a better bound on the list size in the Guruswami-Sudan algorithm for algebraic geometry codes
    Download  www.math.clemson.edu
    Abstract. Given an algebraic geometry code CL(D, P), the GuruswamiSudan algorithm produces a list of all codewords in CL(D, P) within a specified distance of a received word. The i...

    Improved Bounds on Restricted Isometry Constants for Gaussian Matrices
    Download  ecos.maths.ed.ac.uk
    The Restricted Isometry Constants (RIC) of a matrix A measures how close to an isometry is the action of A on vectors with few nonzero entries, measured in the 2 norm. Specifically...
