    • MMSE decoding for analog joint source channel coding using Monte Carlo importance sampling 

      Hu, Yichuan; García Frías, Javier; Lamarca Orozco, M. Meritxell (2009)
      Text en actes de congrés
      Accés obert
      We investigate the performance of a discrete-time all-analog-processing joint source-channel coding system for the transmission of i.i.d. Gaussian sources over additive white Gaussian noise (AWGN) channels. At the encoder, ...

    • Non-linear graph-based codes for joint source-channel coding 

      Matas Navarro, David; Lamarca Orozco, M. Meritxell; García Frías, Javier (2010)
      Text en actes de congrés
      Accés obert
      We study the behavior of a new family of nonlinear graph-based codes, previously introduced for compression of asymmetric binary memoryless sources, for the joint source-channel coding scenario in which the codewords are ...

    • Non-linear graph-based codes for source coding 

      Matas Navarro, David; Lamarca Orozco, M. Meritxell; García Frías, Javier (2009)
      Text en actes de congrés
      Accés obert
      We introduce a new family of graph-based source codes that can be regarded as a nonlinear generalization of LDPC codes, and apply them to the compression of asymmetric binary memoryless sources. Simulation results and 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, ...
