Doctoral Researcher in Wireless mMIMO Signal Processing - Hiring in process/Finished, not possible to apply

We are now looking for

Doctoral Researcher

to join us in the Centre for Wireless Communications - Radio Technologies at the Faculty of Information Technology and Electrical Engineering, the home of the 6G Flagship.

About the job

The wireless communications community is looking towards higher frequencies to achieve even up to multi-hundred-gigabit link speeds. Especially above 100 GHz frequencies, beamforming gain plays a major role in the establishment of the connections. This promotes using large antenna arrays that, on the other hand, allow flexible beamforming in the general case. The term massive multiple-input multiple-output (mMIMO) is often used in conjunction with research involving very large antenna arrays (with hundreds of antenna elements).

The mMIMO gives great benefits in gain and spatial multiplexing of users but comes with challenges in optimizing the beamforming. While the achievable gains can be very large, it is often challenging to estimate and track the channels. This is particularly difficult at +100 GHz, where large antenna gains are always needed. Some of these challenges are hoped to be alleviated by joining sensing and communications to obtain extra information about the channel and predict its behavior.

This doctoral research work will involve utilizing sensing and signaling in enhancing the prediction of channels and interference in order to

1. improve the energy efficiency of the network,
2. improve the beamforming gain at the receiver, and
3. improve the tracking of the users for localization and channel prediction.

This work is related to the European Union (EU) Smart Networks and Services Joint Undertaking (SNS JU) project TERA6G, which is focusing on the development of photonic-based THz mMIMO transceivers and communications algorithms.

As a doctoral researcher, you will be part of a strong and experienced team specialized in signal processing in modern wireless communication systems.
