Topographical instability of event-related potentials in P300 wave study
Microstate analysis of ERP and EEG topographies reveals stable patterns of brain activity. Little is known about the changes from one stable state to another. During such changes significant topographic instabilities are observed together with low ERP fiel ...
2011Non-binary LDPC codes and EXIT like functions
In the first part of this thesis we are interested in the asymptotic performance analysis of Non-Binary Low-Density Parity-Check (NBLDPC) codes over the Binary Erasure Channel (BEC) decoded via the suboptimal Belief Propagation (BP) decoder as well as the ...
EPFL2008Belief Propagation Decoding for Codes Based on Discretized Chaotic Maps
In this paper a class of discretized piecewise linear chaotic maps of a very high dimensions are used for communication over a noisy channel. An information payload that is sent over a channel is controlled in the transmitter and is related to the symbolic ...
2006Chaotic map perturbation control trellis coded modulation
Martin Hasler, Thomas Schimming
In this paper, the authors examine the use of chaotic systems based on the iteration of 1-D and 2-D piecewise linear chaotic maps in a coded modulation scheme. In the proposed scheme, the transmitted information is imposed on the dynamics of the chaotic sy ...
2003Coded modulations based on controlled 1-D and 2-D piecewise linear chaotic maps
Martin Hasler, Thomas Schimming
In this paper, the authors examine the use of chaotic systems based on the iteration of 1-D and 2-D piecewise linear chaotic maps in a coded modulation scheme. In the proposed scheme, the transmitted information is imposed on the dynamics of the chaotic sy ...
2003Potential of chaos communication over noisy channels - Channel coding using chaotic piecewise linear maps
Martin Hasler, Thomas Schimming
The paper gives an information theoretic analysis of the potential of chaos in digital communication schemes, underlining that there is no fundamental principle that speaks against the use of chaotic systems in digital communications. The channel model con ...
