Abstract
In this paper we propose a new algorithm for hyperchaotic spread spectrum sequences selection. Firstly, binary hyperchaotic spread spectrum sequences are generated by a 6-order cellular neural network (CNN). Secondly, we analyze the properties of the sequences according to the P-values and correlation function. Finally, a new algorithm proposed for hyperchaotic spread spectrum sequences selection is based on the properties of hyperchaotic sequences. In order to prove the effectiveness of the proposed selection algorithm, some of the selected hyperchaotic sequences are applied in direct sequence code division multiple access (DS-CDMA) system. Simulation results show that the selected hyperchaotic sequences have better performance than m-sequences and have similar performance with Gold sequences. Compared with m-sequences or Gold sequences, hyperchaotic spread spectrum sequences are better suitable for secure communication systems.
