Columbia University, New York, NY Politecnico di Torino, Torino, Italy 3 Peking University, Beijing, China 4 Instituto Superior Tecnico, Lisbon, Portugal 2 Impulse Radio-UWB (IR-UWB) is actively being researched as a low cost wireless technology for Ultra Low Power (ULP), low data-rate, short-range wireless links in tagging [1], sensing and medical applications. In current solutions efficient timing acquisition as well as Narrow-Band Interference (NBI) rejection requires complex or large analog and digital circuits [2-4]. In this work, we introduce an IR-UWB architecture with very high NBI rejection and present a low complexity and low power timing synchronization and demodulation technique while achieving excellent link performance. Deep power duty cycling can be achieved more easily for IR-UWB transmitters than receivers. Receivers further need to operate with low noise, filter interference and synchronize to the incoming signal and, as a result, often require 10x
