Spread spectrum technique becomes one of the most important communication techniques in the recent decades. It provides high security, in addition to its resistance to the various interference and fading types. One of the most important parameter in the spreading process is the spreading code used in the spreading process, especially in the direct sequence spread spectrum. Recently, many researches focused on the chaotic codes, due to its attractive security properties, in addition to its availability to generate a huge number of spreading codes. This property is very useful in the multi-access applications. However, as the number of the MAI is increased, the performance of the chaotic codes is degraded. This paper presents a new method to generate a set of orthogonal self-balanced chaotic codes. The results show that the presented method generates a set of chaotic codes with correlation properties much better than the traditional chaotic code. The results show also that the BER performance of the presented orthogonal chaotic codes is superior and outperforming the BER performance of the traditional chaotic codes in addition to the PN sequences.
