A novel method for distance estimation is introduced, 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 a transmitter and a receiver with a very good precision and accuracy. The technique effectiveness is demonstrated in a real operating environment by measuring the distance between two active devices and using a pair of Right-Hand circularly polarized helical antennas, achieving a mean final error of 2.94 cm and a mean standard deviation of 0.95 cm with only 20 MHz of bandwidth. The proposed technique can be used in the implementation of indoor positioning systems.

Abstract
A novel method for distance estimation is introduced, 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 a transmitter and a receiver with a very good precision and accuracy. The technique effectiveness is demonstrated in a real operating environment by measuring the distance between two active devices and using a pair of Right-Hand circularly polarized helical antennas, achieving a mean final error of 2.94 cm and a mean standard deviation of 0.95 cm with only 20 MHz of bandwidth. The proposed technique can be used in the implementation of indoor positioning systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
