    • Analysis of LDPC code syndrome entropy based on subgraphs 

      Matas Navarro, David; Lamarca Orozco, M. Meritxell (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés obert
      We propose a method to bound the syndrome entropy of linear block codes from their factor graph representation. It is specially suited for sparse graphs such as those of low density parity check codes. It is based on the ...

    • Progressive encoding with non-linear source codes for compression of low-entropy sources 

      Ramírez Javega, Francisco; Lamarca Orozco, M. Meritxell; García Frías, Javier (2010)
      Text en actes de congrés
      Accés obert
      We propose a novel scheme for source coding of non-uniform memoryless binary sources based on progressively encoding the input sequence with non-linear encoders. At each stage, a number of source bits is perfectly recovered, ...
