In order to decrease the signal length and transmitting time, improve accuracy of the delay time estimate, complete the mission of ranging and communication at the same time, a new ultra wideband (UWB) ranging method is developed in this paper. This method modulates the training sequence and information signals respectively on two carrier waves which are(More)
In CPS (cyber-physical systems), computation is integrated with physical processes, computer system is used to monitor and interact with the physical world to realize maximization of benefit and usage. The model and verification for cyber physical systems are two important and challenge problems because CPS has not only heterogeneous nature but also very(More)
