Abstract: An Ultra-Wideband (UWB) wireless communication device includes a scanning circuit, an ordering circuit, and a selecting circuit. The scanning circuit is configured for scanning at least a channel supported by the communication device for detecting a plurality of patterns of a UWB frame format. The ordering circuit is configured for ordering the plurality of patterns in a patterns list according to a predefined quality parameter. The selecting circuit is configured for selecting at least one of the patterns in the list to start an Ultra Wideband (UWB) wireless communications.
