“…As an alternative far-field transmission method, impulse radio ultrawideband (IR-UWB) transmission has emerged recently due to its low power consumption in the range of a few tens of picojoule per bit (pJ/b) [165]- [167]. Avoiding generation of a carrier with an accurate frequency, noncoherent IR-UWB transmitters generates short pulses with ON-OFF keying (OOK) or pulse position modulation (PPM).…”

Abstract-Synchronization performance of a pulse-based ultrawideband (UWB) system is investigated by taking into account of distortions caused by transmitter and receiver antennas and wireless propagation channels in different environments. The synchronization scheme under consideration can be achieved in two steps: a slide correlator and a phase-locked loop (PLL)-like fine tuning loop. Effects of the non-idealities are evaluated by analyzing the distortion of the received UWB pulse and subsequently the synchronization performance of the pulse-based UWB system. It is found that generally a smaller step is required for the sliding correlator due to distortions introduced by the antennas and channels. However, the fine tuning loop can always be stabilized by adjusting the loop parameters. Therefore, synchronization can always be achieved.

“…Since Pulsed Ultra Wide Band (UWB) technology has become available for unlicensed communication, a broad spectrum of ideas have been presented over the past decade with regard to UWB pulse modulation, generation and detection techniques [1]. Recent literature has primarily demonstrated the potential all-digital UWB transmitters have in achieving ultra low power budgets by operating with aggressive duty cycles while maintaining substantial data rates.…”

Abstract-The paper presents a novel ultra low power UWB transmitter system for near field communication in transcutaneous biotelemetries. The system utilizes an all-digital architecture based on minising the energy dissipated per bit transmitted by efficiently encoding a packet of pulses with multiple bits and utilizing oscillator referenced delays. This is achieved by introducing a novel bi-phasic 1.65 pJ per pulse UWB pulse generator together with a 72 µW DCO that provide a transmission bandwidth of 77.5 Mb/s with an energy efficiency of 890 fJ per bit from a 1.2 V supply. The circuit core occupies a compact silicon footprint of 0.026 mm 2 in a 0.18µm CMOS technology.
