What we offer

The researcher position is based in Massy close to a major transportation hub.

Nokia offers flexible and hybrid working schemes, continuous learning opportunities, well-being programs to support you mentally and physically, opportunities to join and get supported by employee resource groups, mentoring programs and highly diverse teams with an inclusive culture where people thrive and are empowered.

What you will learn and contribute to

The future optical fiber communication networks will be more dynamic in routing traffic, choosing signaling schemes and controlling transmit power to enable maximum utilization of existing infrastructure. To achieve this, massive monitoring of various parameters that can affect system performance is required. Among these parameters is noise which can be broadly categorized as linear and nonlinear noise. An optimal performance can be achieved by maintaining a right balance of linear and nonlinear noise in the link. Therefore, estimation of these noise proportions is crucial.

In this internship, you will join a unique worldwide-recognized team to investigate various methods for noise estimation and transmit power optimization. Your first task will be to study the research literature to understand the existing solutions. It will also give you an overview of linear and nonlinear effects impacting the transmitted signal in an optical fiber. A second task will be to implement new noise estimation methods based on the latest machine learning advances and compare them with existing methods. Furthermore, you will have the opportunity to participate in lab experiments to evaluate the performance gain. 

As part of our team, you will:

Study research literature on nonlinear noise estimation and identify opportunities  Develop noise estimation methods and compare them against benchmark through simulations  Utilize the developed methods to perform launch power optimization  Participate in lab experiments to evaluate the proposed methods
