Performance of a Communicating Radar using FSK and Fractional Fourier Transform for Automotive Applications

In automotive environment, it is preferable to have a joint radar and communication system as it is able to use the same hardware and band of the spectrum for both systems. In this paper a joint radar communication system for automotive radar based on the Fractional Fourier Transform (FrFT) is presented. The performance of the system is analysed in the presence of interference arising from other users. In addition, the communication performance in terms of Bit Error Rate (BER), is analysed for different scenarios. Simulation results demonstrate the potential of the proposed system in multi-user scenarios and in different types of communication channels.
