Abstract

Design of collaborative/multipurpose signal processing/physical layer techniques

The use of non-orthogonal spectrum sharing techniques along with the expectation for massive connectivity demand, not only allows for the efficient exploitation of bandwidth resources by multiple users, but also contributes towards creating an interference-rich environment that can be used by power-limited users for energy harvesting purposes. With this in mind, this PhD thesis will investigate the design of physical layer (e.g. beamforming) techniques aiming at tackling the multifaceted problem of minimizing power consumption while satisfying 1) throughput constraints as set by active (content requesting) users, as well as 2) received/harvested energy constraints as set by power-limited RF-energy harvesting users.

Scenarios accounting for limited Channel State Information (CSI) availability will be considered, as well as scenarios accounting for different levels of CSI availability. Initially, the focus will be on the design of techniques not presuming Base Station collaboration. Extending this initial approach, the aim will shift towards investigating the benefits of Base Station collaboration. Different collaboration policies will be considered exploiting: 1) Energy based collaboration exploiting architectures for jointly handling/trading renewable energy resources commonly accessible to the network base stations, 2) Spectrum based collaboration based on the use of Multicell designs exploiting Multicell-MIMO techniques. The benefits and limitations of system designs based on these two policies will be investigated, and best practices accounting for CSI exchange and computational complexity limitations will be recognized.

Expected Qualifications for candidates

Applicants for the PhD position (3 years) must have undergraduate and/or postgraduate studies on a topic related to wireless communications (e.g. Electrical and/or Electronic Engineering), good background on digital/wireless communications and signal processing for wireless communications as well as strong mathematical skills. French speaking and/or writing is not required but may be a plus.

Location

The thesis will be carried out at Signals, Communications & Embedded Electronics (SCEE) research group (http://www.rennes.supelec.fr/ren/rd/scee/) in CentraleSupelec premises (Campus of Rennes), in France, colocated on the same campus with University of Rennes 1.

Grant

The grant is a “contrat doctoral” from French Ministry of Research, which is set to 1400 € net/month.

Application

To apply send your CV (including contact details, and references letters), copies of degree certificates, academic transcripts, and English language test certificates (if applicable) along with a motivation letter to:
Georgios ROPOKIS (ropokisg@tcd.ie and gropokis@gmail.com) and Christophe MOY (christophe.moy@univ-rennes1.fr)

as soon as possible, in order to start interviews, but anyway before the 20 of May 2018. An interview (Skype or visit) will have to be done with both advisors before the 1st of June. Please indicate if you can come or should do this interview remotely (by Skype or other).

Ecole Doctorale MathSTIC will inform candidates on the final decision to give the grant no later than the 22th of June
