Abstract
In asynchronous direct sequence-code division multiple access (DS-CDMA), the chaotic spreading code is theoretically effective in reducing the bit error rate (BER), and its performance has been shown through computer simulations. In this study, we implement and evaluate the chaotic CDMA system using the software-defined radio technology. By the results of our experiments, clarified that the chaotic spreading code leads to a lower BER than that of the conventional spreading code, as well as in our implemented wireless systems.
