Abstract :
The use of chaotic spreading sequences is a new approach for DS-CDMA systems. Some chaotic PN spreading sequences show better correlation properties than conventional binary PN sequences, which are crucial for the BER performances. This paper is presenting a selection criterion for optimal sets of PN chaotic sequences, which are generated from periodic orbits of a particular class of chaotic dynamics. Finally, their BER performances in a synchronous DS-CDMA system are compared for two particular cases to show the superiority of chaotic sequences.
