Performance Analysis of the Energy Detection Based ToA Estimator for MB-OFDM UWB
نویسندگان
چکیده
The Cramer-Rao Bound (CRB) analysis shows that ultra-wideband (UWB) technique can provide precise timing and positioning, thanks to its huge bandwidth. In this paper, we apply the UWB signal for the energy detection based time-of-arrival (ToA) estimation. We analyze the mistiming performance of the ToA estimator in a general Nakagamim channel. Analysis shows that the slope of the probability of mistiming curve increases as the number of subbands increases. This is known in communications as diversity. Simulations are also carried out to corroborate our theoretical analysis.

We propose a new approach for timing synchronization estimation with polarity comparison for multi-band orthogonal frequency division multiplexing (MB-OFDM)-based UWB systems. We attempt to locate the start sample of frame sequences by calculating difference of the two cross-correlation functions, between received symbols, the successive received symbols, and predefined preamble sequence. It ma...

Problem statement: The Multiband Orthogonal Frequency Division Multiplexing (MBOFDM) Based Ultra Wideband system (UWB) is highly susceptible to symbol timing error. Symbol timing estimation in MB-OFDM based UWB is difficult due to the presence of strongest path at delayed instant. Approach: Symbol timing estimation has two steps namely a coarse estimation and a fine estimation. In this study, a...
