Summary:
In this paper, a new hierarchical CSK(code shift keying)-MPPM(multi-pulse pulse modulation) system is proposed. The system improves reliability of intelligent transport systems. Although it is difficult to set the optinum threshold value, many conventional hierarchical systems use the threshold detector. The proposed system demodulates both of signals by comparative decision. In this paper, the bit error rate of the proposed system and the conventional MPPM-CNK(code number keying) is evaluated. It is shown that CSK-MPPM outperformes MPPM-CNK under the complete synchronization.
