Abstract
In this paper, a chaos-based sequence generator with the multidimensional chaotic system is designed because the sequence generated by the unimodal map can be attacked easily. Some modifications are introduced to the n-dimensional nonlinear digital filters in order to improve the period and distribution property of the resulted sequence. The property of the generated chaotic sequences is similar to that of pseudo-noise (PN) sequences. Test results show that the generator produces sequences with a large code family, good randomness and high security. Chaotic sequences are thus very attractive for satellite spread spectrum systems.
