  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We show how to build full-diversity product codes under both iterative encoding and decoding over non-ergodic channels, in presence of block erasure and block fading. The concept of a rootcheck or a root subcode is introduced ...
  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    A new graph-based construction of generalized low density codes (GLD-Tanner) with binary BCH constituents is described. The proposed family of GLD codes is optimal on block erasure channels and quasi-optimal on block fading ...
  • Boutros, Joseph Jean; Guillén i Fàbregas, Albert; Biglieri, Ezio; Zémor, Gilles (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    We design powerful low-density parity-check (LDPC) codes with iterative decoding for the block-fading channel. We first study the case of maximum-likelihood decoding, and show that the design criterion is rather straightforward. ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper presents our investigation on iterative/ndecoding performances of some sparse-graph codes on block-fading Rayleigh channels. The considered code ensembles are standard LDPC codes and Root-LDPC codes, first ...
  • Andriyanova, Iryna; Biglieri, Ezio; Boutros, Joseph Jean (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    This paper derives approximations allowing the estimation of outage probability for standard irregular LDPC codes and full-diversity Root-LDPC codes used over nonergodic block-fading channels. Two separate approaches are ...
