We are seeking an outstanding and highly motivated Ph.D. researcher to join our research program in the area of localization for 5G cellular networks. The researcher will be involved in the design of the localization system, its numerical simulation and its experimental implementation. The candidate is expected to work with the other members of the Wireless Communications Group at the Université Libre de Bruxelles (U.L.B.) and with our external collaborators.
While existing 3G/4G cellular systems are mainly designed to support communications with broadband mobile terminals, emerging 5G cellular systems will also integrate massive communications with narrowband Internet-of-Things (IoT) nodes. Besides the communication functionality, localization is one of the most fundamental problems in IoT networks, since the position estimates of the nodes and their accuracy are critical parameters to enable network operations and support IoT applications.
Traditional localization approaches based on the estimation of the signal time-of-flight (ToF) cannot be applied to estimate the position of the IoT nodes as their communication bandwidth is too small to achieve acceptable estimate accuracy. Furthermore, if the nodes are deployed in an indoor environment, the localization accuracy is strongly degraded by the multipath propagation inherent to the channel.
The project targets the design and prototyping of a localization system for ultra-low power (ULP) IoT sensors in an indoor environment. The system makes use of a network of radio heads (RH’s) deployed in the environment and used as ‘anchors’ of known location. To ensure efficient localization, the RH’s must be densely deployed and equipped with antenna arrays. This opens the door to localization algorithms based on the estimation of the angle-of-arrival (AoA) of the radio-frequency (RF) signals transmitted by the sensors. In addition to the this, the location estimate will be provided with a measure of its uncertainty.
Applicants should submit before June 30, 2017 via e-mail a curriculum vitae, the contact information for at least one reference, and a copy of the master thesis to: firstname.lastname@example.org.
