Abstract

This paper presents a novel localization method in multiple-input multiple-output (MIMO) systems based on the implementation of passive repeaters. In addition to their ability to enhance performance in MIMO systems by enriching scattering in line-of-sight MIMO environments, and extending coverage area and accessing blind spots in none line-of-sight MIMO environments, passive repeaters can help in localizing users by taking advantage of their spreading in the communication environments. In the proposed method, the target area is divided into a grid. Each location in this grid has a unique field interference created by repeaters. Because of the unique field interference, each location causes a unique field signature at the base station when a user in that location transmits signals. The field signature corresponding to the center of each grid cell is used as a fingerprint for localizing users in that cell, and for all cells, a bank of matched filters corresponding to all stored fingerprints is constructed. Using only the spatial coherence of the measured fields, there is no need for synchronization between users and the base station. When a signal arrives at the base station, the generated field signature is correlated with the bank of matched filters, and the location is determined based on the maximum correlation value. The numerical analysis is performed to verify the validity of the proposed method, and it is found that by means of passive repeaters, the user location can be determined with no need of calculating additional parameters.
