Time synchronization based on IEEE 1588 synchronization protocol aims to synchronize the slave clock to the master clock. Conventional synchronization algorithm focuses on calibrating offset of the slave clock with respect to the master clock. In this paper, a novel method of time synchronization is proposed, the proposed method improves the synchronization(More)
Aiming at path planning of mobile robot under part of dynamic unknown environment, there are some shortages in the aspects of produce of initial population and the structure of specific genetic operator in current used genetic algorithms. In this paper, using the position feedback and forecast of moving direction of obstacle, we present a new method of(More)
This letter presents an adaptive denoising method based on the singular value decomposition (SVD). By incorporating a global subspace analysis into the scheme of local basis selection, the problems of previous adaptive methods are effectively tackled. Experimental results show that the proposed method achieves outstanding preservation of image details, and(More)
Diagnostics of incipient faults for analog circuits is very important, yet very difficult. Traditionally, the soft faults can only be diagnosed under the occurrence of large variation of component parameters. In this paper, a novel approach for diagnosing incipient faults in analog circuits is proposed. First, a statistical property feature vector composed(More)
—The IEEE 802.16 standard is supposed to provide a wide-range broadband wireless service, but it leaves the implementation of the wireless resource scheduler as an open issue. We have studied the scheduling problem and propose a two level scheduling (TLS) scheme with support for quality of service and fairness guarantees for downlink traffic in a WiMAX(More)
