Short Description

For conventional localization systems, multipath propagation is considered a serious impairment, since it can bias distance estimates. However, if some knowledge of the surrounding environment is available, reflected signal paths can be effectively used for localization [1]. This multipath-assisted localization and tracking concept is based on measurements between anchors (base-stations) with known positions and moving agents. In [2] an algorithm for cooperative multipath-assisted localization was investigated, which is making use of measurements and also monostatic bat-like measurements. These bat-like measurement can be seen as Radar measurements in which the transmitter and the receiver are co-located. However, this method was just tested and validated using synthetic data.

The goal of this project/thesis is to incorporate bat-like monostatic measurements in an existing multipath-assisted localization framework and verify the applicability of the designed localization algorithm using (existing) measurement data.

Your tasks:

• Extent existing Matlab localization framework to bat-like measurements
• Validation of localization algorithms using synthetic data based on an existing channel model
• Testing and evaluation of localization algorithms using (existing) measurement data

Your Profile

• Motivation and reliability are a prerequisite
• Matlab programming skills
• Good background in wireless communications (e.g. Mobile Radio Systems course)
