Description
MULTI-POS is a Marie Curie ITN funded by the European Commission that will address challenging research topics in the field of wireless localization and will offer a comprehensive multi-dimensional and cross-boundary training to 15 selected researchers from all over Europe. The objectives of MULTI-POS network are: to bridge the gap between the lower technology layer and the upper application layer involved in wireless mobile positioning and navigation, to create novel methods, technologies and business models for the future location-enabled wireless devices, to improve the career perspectives of selected researchers in both public and private sectors, and to create a community of researchers capable of exploiting synergies and complementarities between various fields involved in location and navigation, such as engineering, social sciences, and business. This job opportunity is focused on improving navigation technology through advances in signal design and processing techniques. Objectives:
- Design of signals and algorithms that offer good and controllable performance for combined positioning and communication systems.
- Derivation of metrics and robust techniques for integrity at signal-processing level
The objective of the activity is twofold. First, the ESR will improve some of the design techniques developed in the UAB research group for signals with good capacity for conveying information and providing accurate timing measurements. After gaining some knowledge about the current design techniques, the ESR objective is to modify the techniques to overcome some of the simplifying assumptions that are used at present. The ESR will compare the positioning and communication capabilities of the new and existing designs. Second, the ESR will study the robustness of the signals in non-ideal propagation conditions, mainly taking into account the presence of NLOS, interference, spoofing, BOC-induced ambiguities. Once the faults affecting the signal are understood and s/he is able to identify them, the ESR will have to derive robust acquisition and tracking techniques for such conditions, as well as detectors of the presence of NLOS, interference and spoofing. These techniques will include confidence metrics bounding the errors. The ESR will propose ways to determine the confidence levels on the performance of NLOS, interference, etc. detectors and mitigation techniques, as well as estimates of the correct acquisition probability and of the tracking errors. The study will be mainly targeted to positioning in urban environments. The ESR will analyse the robustness of the acquisition and tracking in realistic scenarios and with real samples captured using in-house equipment. The ESR will be seconded to CUT (Chalmers University of Technology) and GMV in order to learn from CUT about the application of cooperative localization techniques to combined systems and to take advantage of the expertise of GMV on both positioning in urban environments and integrity.
Expected Results:
- Method to design a signal with communication and positioning capabilities; assessment of those capabilities.
- Techniques proposed for detection of feared events at signal-processing level: NLOS, interference and spoofing. Confidence metrics identified to bound the errors in the acquisition and tracking phases and to quantify the success probability of the detectors.
- Validation and characterization of the previous techniques using real data including some
- One technical report for each of three bullets above.
The ESR is expected to publish at least one conference paper per year and one journal paper in the whole fellowship duration, in conference and journals related to signal processing or navigation, mainly organized or edited by IEEE (preferred option), ION or ESA. Reusing material from the reports and publications, s/he will compile a PhD thesis. The recruited fellow will have the possibility of making patent applications if innovative techniques with industrial interest are developed. The recruited fellow is expected to participate in efforts to reach out to the society by public presentations, preparation of dissemination material and demonstrations.
Requirements
We are looking for highly motivated, enthusiastic junior scientists, with a preferential background in one or more of these areas: positioning technologies, communications technologies, electrical engineering, telecommunications engineering, or mathematics.
