Abstract

Using the high-dimensional complex chaotic system in the chaotic ultra wideband signal can enhance the security of the signal, but reduce the easy implementation of the chaotic system. In view of the contradiction between the complexity and the easy realization of the chaotic system used in the chaotic ultra wideband(UWB), this paper designed a chaotic system with low dimension and easy to implement by using two one-dimensional chaotic maps with easy implementation based on chaos branch switching and embedding. Lyapunov exponent analysis shows that it is chaotic in a wide range of parameters. The analysis shows that the signal generated by the system cannot reflect the definite mapping relation, which not only increases the complexity of chaotic signal, but also makes the system easy to implement. The analysis also shows that this chaotic signal has good correlation. Therefore' this paper also generated more secure chaotic time hopping UWB signal based on this chaotic system. At the same time, through the comparative analysis of the power spectrum of the chaotic UWB signal and the general pseudo-random time hopping UWB signal, it contains less discrete spectrum which can produce interference to other transmission systems, and also makes the chaotic UWB signal have more extensive application fields.
