  سند علمی۲۰۰۴Alexander Vardy, Mario Blaum, Paul H. Siegel, Glenn T. Sincerbox

  AbstructIn holographic storage, two-dimensional arrays of binary data is optically recorded in a medium via an interference process. To ensure optimum operation of a holographic recording system, it is desirable that the patterns of 1’s (light) and 0’s (no light) in the recorded

• An Efficient Algorithm for Constructing Minimal Trellises for Codes over Finite Abelian Groups - Information Theory, IEEE Transactions on

  سند علمی۲۰۰۴Vijay V. Vazirani

  We present an efficient algorithm for computing the minimal trellis for a group code over a finite abelian group, given a generator matrix for the code. We also show how to compute a succinct representation of the minimal trellis for such a code, and present algorithms that use t

  سند علمی۱۹۹۹T. V. Selvakumaran, B. Sundar Rajan

  A length n group code over a group G is a subgroup of G under component-wise group operation. Two-level group codes over the class of generalized quaternion groups, Q2 ; m 3, are constructed using a binary code and a code over Z 2 , the ring of integers modulo 2 m , as component

  سند علمی۱۹۹۶Mario Blaum, Jehoshua Bruck

  AbstructA new family of MDS array codes is presenled. The code arrays contain p information columns and T indelpendent parity columns, each column consisting of p 1 bits, where p is a prime. We extend a previously known construction for 1 he case T = 2 to three and more parity co

• Price's Theorem for Complex Variates [Correspondence] - Information Theory, IEEE Transactions on

  سند علمی۲۰۰۴A. van den Bos

  Price's theorem is derived for complex valued variates. The derivation differs from the existing derivation in two respects. First, the normal variates are not assumed to be circularly complex. Thus the result is more general. Second, the characteristic function of the complex va

• Modulation and Coding for Linear Gaussian Channels - Information Theory, IEEE Transactions on

  سند علمی۱۹۹۸G. David Forney

  Shannon’s determination of the capacity of the linear Gaussian channel has posed a magnificent challenge to succeeding generations of researchers. This paper surveys how this challenge has been met during the past half century. Orthogonal minimumbandwidth modulation techniques an
