This PhD thesis will contribute to the French ANR project DUPLEX, "Full-Duplex MIMO Techniques for the Future Wireless Networks"

Full-duplex consists in transmitting and receiving simultaneously in the same frequency band, which in theory allows to double the capacity of communication. The DUPLEX project objectives are:

-to study the theoretical limits (throughput) of full-duplex communication equipment, and in particular in the case of a Multiple Input Multiple Output (MIMO) equipment

-to develop antenna techniques, analog and digital processing for the cancellation of the transmitted signal at the receiver

-to develop a MIMO full-duplex communication equipment (prototype) for the next generation of communications.

The project addresses two scenarios:

-full-duplex communication between two communication nodes. In this case, the signal cancellation device uses the knowledge of signal, assumed to be known

-full-duplex relaying, in which the relay processes, amplifies and retransmits the received signal in the same band. In this scenario, several cases will be considered depending on the information to be relayed (i.e. decodable or not).

Research Topics of this PhD thesis

This thesis will focus both on self-interference cancellation and on multi-antenna transceiver techniques for wireless systems containing full duplex radio units.

Self-interference cancellation topics:

  • We will in particular focus on pushing the limits of digital cancellation techniques, by modeling of non-linearities. Compressed sensing techniques will be used for the model determination.
  • For the adaptation of digital filters, some attention will go to the relaying scenario, which represents a case of strong correlation between filter input and filter error.
  • Extension to hybrid architectures: digital solutions cannot work alone

Multi-antenna transceiver techniques:

  • FD MIMO Self backhauling in 5G
  • (MIMO) relaying for interference reduction:

Design and analysis of multi-user multi-cell interference networks with MIMO relays, with mixed half and full duplex nodes.

  • Two-way spatial filter training (exploiting reciprocity):

Bidirectional training schemes that use transmission over the channel to do fast filter computations, allowing superfast in-network transceiver adaptation with simultaneous transmission.

Requirements:We are looking for a highly motivated person with a master degree in electrical engineering with a strong background in applied mathematics and signal processing as well as excellent programming skills (Matlab). Previous experience in the area of statistical signal processing, possibly applied to wireless radio communications will also constitute a significant advantage. English language and general communication skills also constitute a plus.

EURECOM:EURECOM is a Graduate School and a Research Center in Communication Systems, located in the Sophia Antipolis technology park on the Côte d’Azur in France, in close proximity to a large number of research units of leading multinational corporations in the telecommunications, semiconductor and biotechnology sectors, as well as other outstanding research and teaching institutions. EURECOM was founded in 1991 by TELECOM ParisTech (Ecole Nationale Supérieure des Télécommunications) and EPFL (Swiss federal institute of technology of Lausanne) in a consortium form, combining academic and industrial partners.

EURECOM deploys its expertise around three major fields: Digital Security, Data Science and Communication Systems (formerly: Mobile Communications) and has a strong international scope and strategy. EURECOM is particularly active in research in its areas of excellence while also training a large number of doctoral candidates. Its contractual research is recognized across Europe and contributes largely to its budget.
