Ultra-wideband (UWB) is a radio technology that can be used at very low energy levels for short-range high-bandwidth communications by using a larger portion of the radio spectrum. UWB is used for transmitting information spread over a large bandwidth (> 500 MHz). A significant difference between traditional radio transmissions and UWB radio transmissions is that traditional systems transmit information by varying the power level, frequency, and/or phase of a sinusoidal wave. UWB transmissions transmit information by generating radio energy at specific time instants and occupying large bandwidth thus enabling a pulse-position or timemodulation.[1]

UWB devices are expected to operate at rates of up to 0.5 Gb/s and communicate with other devices at a range of up to 10 m, thus enabling high-speed wireless personal area Networks (WPANs). UWB devices are allowed to operate in an unlicensed manner in the …
