    • Parallelization of the interpolation process in the Koetter-Vardy soft-decision list decoding algorithm 

      Moreira Sánchez, José; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (2012)
      Comunicació de congrés
      Accés obert
      List decoding is a decoding strategy that provides a set of codewords at the output of the channel decoder. Since this technique corrects errors beyond the correcting bound of the code, upper layers in the application or ...
    • Recobriment i grafs distància-regulars 

      Rifà i Coma, Josep; Pujol Capdevila, Jaume (Universitat Politècnica de Barcelona. Centre de Càlcul, 1988)
      Article
      Accés obert
      Uno de los aspectos claves en las telecomunicaciones está relacionado con el uso de los códigos correctores de errores para la transmisión de información. Actualmente se utiliza una clase muy simple de códigos; la ...
    • Runtime-guided ECC protection using online estimation of memory vulnerability 

      Jaulmes, Luc; Moretó Planas, Miquel; Valero Cortés, Mateo; Erez, Mattan; Casas, Marc (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés obert
      Diminishing reliability of semiconductor technologies and decreasing power budgets per component hinder designing next-generation high performance computing (HPC) systems. Both constraints strongly impact memory subsystems, ...
    • Signature codes for weighted noisy adder channel, multimedia fingerprinting and compressed sensing 

      Egorova, Elena; Fernández Muñoz, Marcel; Kabatiansky, Grigory; Moon Ho, Lee (2019-03-01)
      Article
      Accés obert
      We propose a new approach to construct noise-resistant multimedia fingerprinting codes. Our approach is based on the theory of the signature codes for multiple access channels, mainly, for a weighted noisy adder channel. ...
    • SRAM arrays with built-in parity computation for real-time error detection in cache tag arrays 

      Canal Corretger, Ramon; Sazeides, Yiannakis; Bramnik, Arkady (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés obert
      This work proposes an SRAM array with built-in real-time error detection (RTD) capabilities. Each cell in the new RTD-SRAM array computes its part of the real-time parity of an SRAM array column on-the-fly. RTD based arrays ...
    • The equivalence of codes 

      Dixon, James Edward (Universitat Politècnica de Catalunya, 2021-07)
      Projecte Final de Màster Oficial
      Accés obert
      When discussing equivalent codes, the literature tends to define equivalence differently for linear or nonlinear codes. For non-linear codes, one normally defines equivalence based on a permutation of coordinates and ...
    • The equivalence of linear codes implies semi-linear equivalence 

      Ball, Simeon Michael; Dixon, James (2022-07-01)
      Article
      Accés obert
      We prove that if two linear codes are equivalent then they are semi-linearly equivalent. We also prove that if two additive MDS codes over a field are equivalent then they are additively equivalent.
    • The geometry of Hermitian self-orthogonal codes 

      Ball, Simeon Michael; Vilar Algueró, Ricard (Springer, 2021-12-20)
      Article
      Accés obert
      We prove that if n>k2 then a k-dimensional linear code of length n over Fq2 has a truncation which is linearly equivalent to a Hermitian self-orthogonal linear code. In the contrary case we prove that truncations of linear ...
    • The geometry of quantum codes 

      Puig Pericas, Pablo (Universitat Politècnica de Catalunya, 2021-07)
      Projecte Final de Màster Oficial
      Accés obert
      Quantum particles are continuously interacting with the environment hence quantum information is always susceptible to errors. Consequently when encoding information into quantum bits a special treatment is required such ...
    • Use of Turbo Codes with Low-Rate Convolutional Constituent Codes in Fingerprinting Scenarios 

      Tomás Buliart, Joan; Gómez Muro, Ana; Fernández Muñoz, Marcel; Soriano Ibáñez, Miguel (IEEE, 2011)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      We discuss the use of turbo codes in fingerprinting schemes. More precisely, we present a family of turbo codes that are secure against attacking coalitions of size 2. This family is build upon a class of low-rate convolutional ...
