“…One possible solution to reduce the power consumption is to place the ADC after the correlator, and hence the correlation is performed in the analog domain. This relaxes the ADC requirements, and consequently reduces the overall power consumption [13]. In particular, moving the correlation operation from the digital domain to the analog domain reduces the required sampling frequency from the Nyquist rate to the pulse repetition rate [13].…”

However, the generation of the optimal template pulse in the analog domain is also difficult and powerconsuming.…”

Abstract-Recently, we proposed a wireless ambulatory gait analysis system that provides a high ranging accuracy using ultrawideband (UWB) transceivers. In this paper, we further investigate the performance of our proposed system including ranging using suboptimal templates, power consumption, and sensor-fusion. We show that the proposed system is capable of providing a 1.1 mm ranging accuracy (11.7 mm for current systems) at a signal-to-noise-ratio (SNR) of 20 dB using suboptimal-based receivers in industry accepted body-area-network UWB channels. For the angular-displacement, our system provides an accuracy that is less than 1 • for the kneeflexion angle. This accuracy is superior to the accuracy reported in the literature for current technologies (less than 4 • ). Finally, we propose the integration of UWB sensors with force sensors. The system performance and design parameters are investigated using simulations and actual measurements. Ultimately, the proposed system is suitable for taking accurate measurements, and for tele-rehabilitation.

“…Generally, ED receivers consume smaller amounts of power as compared to TR and fully digital architectures for the same design parameters. Figure 2 shows a comparison of the power consumption of four different receiver architectures based on the actual implementation parameters presented in [16,17]. As can be seen, ED receivers have the smallest power consumption as compared to TR and fully digital architectures.…”

Abstract-This paper studies the bit error rate (BER) performance of non-coherent impulse-radio ultra wideband (IR-UWB) correlation receivers in the IEEE 802.15.3a channel for combined binary pulse amplitude modulation-pulse position modulation (BPAM-PPM) scheme. The BER performance is based on the channel averaged signal-to-noise ratio (SNR). The study includes simple transmitted reference (TR), differential TR (DTR), and energy detection (ED) receiver structures. Moreover, different performance parameters are addressed, namely the signal bandwidth integration window factor, number of pulses per bit, and receiver power consumption. ED receivers with BPAM-PPM are shown to outperform simple TR receivers and have a performance which approaches that of differential TR (DTR) receivers with smaller power consumption for the same design parameters.

“…For a low data rate UWB link, typically a non-coherent receiver is implemented due to the simplicity in hardware architecture, low power consumption, and low energy efficiency [7][8][9]. However, non-coherent demodulation suffers bandwidth inefficiency and worse sensitivity.…”

Effects of Antennas and Propagation Channels on Synchronization Performance of a Pulse-Based Ultra-Wideband Radio System

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.
