In this paper, we propose to generalize the coding schemes first proposed by Kozic & al to high spectral efficient modulation schemes. To obtain high performing coding schemes, we use a high dimensional modulo-MAP mapping process similar to the low-density generator-matrix codes (LDGM) introduced by Kozic & al. The main difference with their work is that we use an encoding and decoding process...
In this paper, we propose a new insights for the chaos coded modulation (CCM) schemes originally proposed by Kozic & al. using the approximation of the distance spectrum distribution with some usual laws, a complete study of the performances of these CCM schemes when they are concatenated with a Space Time Block Code (STBC) is proposed. Accurate bounds are obtained even in the case of time selective...
Recently, some works have shown that it was possible to obtain quite good BER performances over AWGN channels with chaotic systems. This paper proposes new insights for the chaos-coded modulation schemes originally proposed by S. Kozic et al. A detailed study of the distance spectrum of such schemes is proposed and an approximation of its distribution by means of Gaussian mixtures is given.
