The analyses of an improved 2-order Chebyshev chaotic sequence

This paper proposes a new method to obtain an improved 2-order Chebyshev chaotic sequence, along with the theoretical analysis and the simulation experiments with the sequence. Compared with m sequence in the balance property and the run-length property, the sequence maintains good performance. The findings of theoretical analysis and the experiments show that the improved sequence is better than m sequence application in spread spectrum communication system.
