Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of almost SEK 2.1 billion per year. We are currently 1,900 employees and have 18,700 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope you will help us build the sustainable businesses and societies of the future. The Signal Processing group conducts research in the areas of inference and wireless communication, using both acoustic and radio signals. We now offer an opportunity to participate in a dynamic, international research environment in close collaboration with industry and leading universities worldwide. Subject description The subject covers signal processing with a focus on the development and optimization of algorithms for the processing of one- and multi-dimensional signals that are closely related to applications and applied research. Project description You will participate in a project that conducts research at the intersection of wireless communications, acoustics and signal processing. The project focuses on the challenge of reliable high-speed communication with small, energy-free sensors or other devices, using acoustic and ultrasound-based backscatter communication techniques. The project has a broad approach that includes both the creation of basic understanding of acoustic backscatter communication and the development of a prototype demonstrator in our communication/ultrasound laboratory. We expect the results in both of these areas to result in scientific publications in highly ranked journals. Duties and responsibilities The Department of Systems and Space Engineering (SRT) at Luleå University of Technology (LTU) offers a postdoctoral position in signal processing. We are looking for an ambitious and creative colleague with a PhD degree and strong analytical skills, who wants to contribute to cutting-edge research in our field. Qualifications The research will focus on signals in the physical layer and is expected to use methods from communication theory, wave propagation, signal processing and electronics. To qualify for a postdoctoral position, you must have a PhD, a doctoral degree or a foreign degree equivalent to a PhD or doctoral degree in the above or related subjects. We expect candidates to have strongly documented experience and published scientific papers in these fields. Candidates should have excellent knowledge of English, both oral and written. A doctoral degree awarded no more than three years before the closing date for applications is an advantageous qualification. Candidates who have obtained their doctorate earlier may also be considered if there are special reasons, such as various types of statutory leave. Applicants who are close to completing their doctorate are also encouraged to apply. Information on the post The position is fully funded by the Swedish Research Council and is limited to two years, based in Luleå, Sweden. Start date is by agreement between the parties.
