UWB technology has offered a huge application bandwidth and its bandwidth has been reached up to Gbps recently. One of the various UWB specifications, WiMedia Alliance's MAC and PHY can also be used for high-speed multimedia applications to establish wireless video area network (WVAN). In this paper, we propose a gigabit UWB video transmission system for WVAN. To guarantee Gbps operation, we implemented...
A UWB communication transceiver(TRX) named `WiX(Wireless eXpress) TRX' is proposed, which is featured with three WiMedia UWB RF channels and a new small planar type OMUX, for high data rate TX and RX. Each WiMedia UWB RF channel can treat more than 500Mbps wireless data, and the OMUX combines and splits the output and input of three WiMedia UWB RF channels in the TX and RX modes, respectively. The...
Ultra-wideband (UWB) systems use wide band-width of 3.1 to 10.6 GHz to provide ultra high data-rate for wireless applications. Implementation of UWB RF transceiver in the 3-5 GHz band (mandatory mode) makes big challenges that must be solved by circuit and system techniques. The proposed radio frequency (RF) transceiver, which is implemented in 0.13 mum complementary metal-oxide semiconductor (CMOS)...
