ENERGY EFFICIENT ULTRA-WIDEBAND IMPULSE RADIO SYSTEMS AND METHODS

摘要

Ultra-wideband (UWB) technology uses modulated coded impulses over a wide frequency spectrum at very low power over short distances for digital data transmission. Such a UWB system via a receiver may operate in the presence of interfering signals and should provide robust communication. Thus, an accurate and sharp filter operating at low power is required and advantageously the filter does not require a very accurate power intensive clock. In addition, many UWB applications require UWB-based ranging and/or location capabilities that require location and/or range measurements of other devices and thus eliminate the requirement of adding additional device complexity and, in general, significant power consumption. It would be beneficial to provide
