1 Summary At the Electronics and Signal Processing Laboratory at EPFL (formerly UNINE), an experimental platform has been designed and built to demonstrate the feasibility of Ultra-wideband Impulse Radio (UWB-IR) technology applied to indoor positioning [1]. This office-scale demonstrator has proven to be a valuable research tool, with the flexibility to(More)
— In this paper, the bit error rate (BER) performance for an ultra-wide bandwidth (UWB) impulse radio in an additive white Gaussian noise (AWGN) transmission channel and with Gaussian jitter is estimated. The assumed receiver combines the received pulses to increase the signal to noise ratio (SNR) and correlates the received signal with a locally generated(More)
— This paper analyzes the receiver's ability to differentiate between multiple users in ultra-wideband (UWB) impulse radio (IR) during the initial synchronization phase after a cold start, i.e., when the receiver is not yet synchronized with the user of interest. Because of multiple access interference (MAI), the receiver may combine the pulses of other(More)
—In this paper, we consider an impulse-based ultra-wideband (UWB) receiver and assess the performance of different multiple access and modulation schemes, including time-hopping pulse position modulation (TH-PPM), time-hopping binary phase shift keying (TH-BPSK), and BPSK-BPSK, under both the additive white Gaussian noise (AWGN) and indoor multipath (CM3)(More)
