The paper introduces a novel method for distance estimation based on an OFDM signal combined with the Zadoff-Chu sequences.

The technique effectiveness is demonstrated by measuring the distance between a single transmitter and a synchronized receiver connected through cables with different lengths. The mean final accuracy of 0.2 cm joint to a mean final precision of 0.65 cm with 100 MHz of bandwidth is achieved.

Abstract

The paper introduces a novel method for distance estimation based on an OFDM signal combined with the Zadoff-Chu sequences. By exploiting the properties of these sequences, it is possible to evaluate the distance between two active nodes with a very good precision and accuracy. The technique effectiveness is demonstrated by measuring the distance between a single transmitter and a synchronized receiver connected through cables with different lengths. The mean final accuracy of 0.2 cm joint to a mean final precision of 0.65 cm with 100 MHz of bandwidth is achieved. The proposed technique can be advantageously used in indoor positioning systems design.
