Abstract

In recent years, several methods have been found to construct chaotic sequences, which have good correlation properties and increase security of the transmission. The length of chaotic sequence can be choosed in terms of the situation, and the balance property can be controlled. In this paper, using the Chebyshev map of third degree, we design a kind of true balanced chaotic sequence in which the number of "+1" and "-1" are equal and apply them into non-coherent OCDMA system with balance complementary structure to reduce the complexity of the system and improve system performance. In terms of BER, our numerical simulations show that systems based on chaotic spreading sequences perform better than Gold sequence.
