Abstract :
In this paper, an effective chaos based non-coherent spread spectrum communication scheme is proposed for inter-vehicle communication in intelligent transportation systems (ITS). The proposed spread spectrum scheme modulates the data to be broadcasted into the bifurcation parameter of the chaotic system and therefore the transmitted signal is broadband. By exploiting the ergodic property of chaotic signals, a simple non-coherent receiver is developed to demodulate the received signal. The new spread spectrum scheme can be implemented using simple hardware and with low manufacturing cost, which is one of the important considerations for communications in an ITS. It is shown here that the proposed chaotic spread spectrum system is highly robust against synchronization error and rapid multipath fading caused by vehicular mobility through computer simulations. Performance analysis illustrate the superior communication performance of the proposed chaotic spread spectrum over the conventional direct sequence spread spectrum scheme for collaborative driving in an ITS.
