Abstract

In order to improve the bit error rate performance of one-dimensional coded modulations using chaotic maps, an optimization process is performed in this paper. Based on the designing methods of conventional trellis coded modulation the minimum free Euclidean distance between signal sequences of chaos-based coded modulations is maximized. Computer search method is then used to find the coded modulations with better minimum distance properties. Finally, bit error rate simulations are given to confirm our optimization results.
