A chaos modulation is a Gaussian modulation that achieves coding gains and physical layer securities. In the conventional method, a Bernoulli shift map, which is a chaos equation, is used for the modulation. However, the coding gain is limited to avoid an increase in the modulation complexity. In this paper, we propose a chaos modulation using a logistic map. Numerical results demonstrated that the proposed method increased the coding gain with the same amount of computation as that of the existing method.
