An Ultra-Low-Power interference-robust IR-UWB transceiver chipset using self-synchronizing OOK modulation

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.
