A Low-Power Receiver Architecture for Interference Robust UWB Radio

摘要

Ultra-Wideband (UWB) wireless communications promises unprecedented levels of seamless connectivity between consumer electronics devices, enabling gigabytes of data to be transmitted in seconds rather than hours without exhausting the batteries of handheld portable devices such as digital cameras, audio jukeboxes and mobile phones. The FCC has already opened up spectrum in the 3.1 GHz to 10.6 GHz range for unlicensed UWB operation, and the WiMedia Alliance (an amalgamation of the WiMedia and Multiband OFDM Alliance SIG groups) is proposing transmission standards that will encourage worldwide acceptance of UWB by accommodating anticipated differences in spectrum allocation from regulatory bodies around the world.
