摘要
The use of chaotic signals as spectral spreading sequences in direct-sequence spread-spectrum (DS/SS) leads to several improvements in communication security and noise elimination. This paper presents a new approach for the design of DS-CDMA system. A digital information signal is modulated using chaotic code shift keying (CSK). The chaotic generator, based on the Lorenz system is slightly modified in order to control the amplitude and frequency of the chaotic signal and synchronized the receiver and transmitter. The results presented show that the receiver is able to recover fully the transmitted information without any degradation and with high security.
