The high implementation complexity of multiband orthogonal frequency-division multiplexing (MB-OFDM) ultra-wideband (UWB) technology is the major hurdle for applying it to vehicular communications. This paper presents a comprehensive synchronizer with low complexity and high performance for the MB-OFDM UWB. A low-complex overall architecture is proposed, in(More)

More and more voice data are generated and transmitted in day and day life in the fields like commercial, military, communication, where include sensitive information which should be protected. Our research concentrates on security(More)
For conventional clustering segmentation of a color image, it is necessary to predetermine cluster number and centers of the color image. If they are not appropriately predetermined, results of segmentation may become considerably worse. To fulfill unsupervised clustering segmentation of visual color images for a mobile robot, this paper proposes a(More)
