Improved Decoding of ReedSolomon and AlgebraicGeometry Codes
 IEEE TRANSACTIONS ON INFORMATION THEORY

"... Given an errorcorrecting code over strings of length n and an arbitrary input string also of length n, the list decoding problem is that of finding all codewords within a specified Hamming distance from the input string. We present an improved list decoding algorithm for decoding ReedSolomon codes ..."

Given an errorcorrecting code over strings of length n and an arbitrary input string also of length n, the list decoding problem is that of finding all codewords within a specified Hamming distance from the input string. We present an improved list decoding algorithm for decoding ReedSolomon codes. The list decoding problem for ReedSolomon codes reduces to the following "curvefitting" problem over a field F : Given n points f(x i :y i )g i=1 , x i

pour i = 1,..., n + k + 2 et S ' En+k−1(Cn), ou ̀ En+k−1(Cn) est le fibre ́ de Schwarzenberger sur Pn appartenant a ̀ Sn,k associe ́ a ̀ la courbe Cn ⊂ P∨n. On en déduit qu’un fibre ́ de Steiner S ∈ Sn,k, s’il n’est pas un fibre ́ de Schwarzenberger, possède au plus (n+ k+1) hyperplans instables; ceci prouve dans tous les cas un résultat de Dolgachev et Kapranov ([DK], thm. 7.2) concernant les fibrés logarithmiques. ABSTRACT — Let Sn,k denote the family of Steiner’s bundle S on Pn defined by the exact sequence (k> 0) 0 → kOPn(−1) − → (n+ k)OPn − → S → 0 We show the following result: Let S ∈ Sn,k and H1, · · ·,Hn+k+2 distincts hyperplanes such that h0(S∨Hi) 6 = 0. Then it exists a rational normal curve Cn ⊂ P∨n such that Hi ∈ Cn for i = 1,..., n + k + 2 and S ' En+k−1(Cn), where En+k−1(Cn) is the Schwarzenberger’s bundle on Pn which belongs to Sn,k associated to Cn ⊂ P∨n It implies that a Steiner’s bundle S ∈ Sn,k, if it isn’t a Schwarzenberger’s bundle, possesses no more than (n + k + 1) unstable hyperplanes; this proves in any case a result of Dolgachev and Kapranov ([DK], thm 7.2) about logarithmic bundles. 1
