ITERATIVELLY DECODING CHAOS ENCODED BINARY SIGNALS
Francisco J. Escribano, Miguel A. F. Sanjuán, L. Lopez · 2006
In the present article we propose a new soft-input softoutput (SISO) decoding module for a chaos-channel encoded binary signal. When the chaos based channel encoder is used as inner encoder and a convolutional encoder is used as outer encoder in a serial concatenation scheme, the signal can be thus iterativelly and jointly decoded by means of the corresponding SISO decoders. This allows the transfer of bit extrinsic information for a nal Maximum a Posteriori (MAP) decoding of the bit information. We believe that the design of this new chaos based SISO decoding module opens a road for new developments to make chaos based communications more robust and efcient.
