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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
