Job Description

Project tasks and objectives: The first objective is to derive the bounds and corresponding trade-offs between communications and positioning capabilities of the networks. We will consider networks that include the presence of hybrid (i.e. with active and passive) structures. The bounds will be used to choose the system parameters optimizing certain application-dependent key performance indicators. Next, channel estimation, sensing and positioning algorithms that are both practical and approach the bounds will be developed. Near-field and wide-band effects will be considered. Special attention will be devoted to the hardware impairments, which are nowadays one of the limiting factors in the use of large antenna systems and intelligent surfaces, since their real behavior strongly deviates from the standard models. The effect of hardware impairments
will be analyzed, and they will be considered in the derivation of robust sensing/positioning algorithms.

The hired researcher will spend the first 18 months at Ericsson (Stockhol, Sweden), the next 3 months at Instituto de Telecomunicaçoes (Aveiro, Portugal), and the final 15 months at Universitat Autònoma de Barcelona (Bellaterra, Spain).

Expected Results: Statistical tools for the performance analysis and optimization of the communications and sensing capabilities of cell-free networks with hybrid intelligent surfaces. Characterization of the effects of hardware impairments. Development of robust low-complexity integrated communications and sensing algorithms.

The position is offered in the frame of the EU-funded MSCA industrial doctorate MiFuture. MiFuture network will develop a high-level personalized multidisciplinary programme to provide 15 Ph.D. candidates, supervised by committed experts from the industry and academia, with research competences and transferable skills (e.g., entrepreneurship, project management, IPR, open access) with the long-term goal to lead scientific advances in the new concepts arising in the field of wireless communications
