A postdoctoral position is open at CEA-Leti in the area of 5G millimeter wave wireless communications, focused on the system level study and implementation of in-band full-duplex mmW radio transceiver.
The CEA-Leti, one of the three advanced-research institutes within CEA Tech, is focused on creating value and innovation through technology transfer to its industrial partners. It specializes in nanotechnologies and their applications, from wireless devices and systems, to biology, healthcare and photonics. With a staff of more than 1,900, Leti is based in Grenoble, France, and has offices in Silicon Valley, California, and Tokyo.
Located in Grenoble at the heart of the MINATEC Campus, the wireless broadband systems laboratory (LSHD) is conducting cutting-edge research in wireless communications for broadband and 5G systems, including advanced channel coding and modulation, transceiver design, access control protocols, and radio and network resource management. Its activities cover a large spectrum, from the specification, simulation and characterization, to the design of both SW and HW components for wireless communications.
As part of these activities, a postdoctoral position is open in the area of 5G millimeter wave (mmW) wireless communications, focused on both system level study and implementation of in-band full-duplex mmW radio transceiver.
The goal of this project is to investigate and design a new mmW radio transceiver for self-backhaul small cells in order to highly increase the capacity of future 5G cellular networks. This transceiver must support interference and self-interference cancellations to be able to deal with classical external interference rejection and full-duplex in-band transmission. Recent demonstrations show that a transceiver can transmit and receive simultaneously in the same bandwidth if it is able to mitigate its self-interference by both analog and digital means (antenna, analog RF and digital). To reach such a goal, the transceiver must consider linear but also nonlinear phenomena over a large bandwidth in the mmW band. The main objectives of the work are the study of cross-domain Self-Interference Cancellation, and the definition of an In Band Full Duplex demonstrator targeting 5G new requirements in mmW frequency bands.
The main tasks are summarized as follows:
