Master’s thesis worker to program transceivers in our 5G millimeter-wave mobile phone antenna testbed

Job description
The fifth-generation (5G) cellular wireless has started its roll out in many countries. Successful deployment of 5G radios require robust user devices that work in varying operational conditions of a mobile environment. Interaction between a mobile phone and operating users poses a particular challenge for 5G because it uses much higher radio frequencies than traditional cellular systems. Antenna arrays operating at millimeter-waves on a mobile phone suffer from much severer shadowing or degradation of efficiency, due to increased losses in diffraction and penetration through the human body. The appropriate real-time characterization of the antennas and arrays in a 5G mobile phone is therefore an unsolved challenge for the cellular industry. The work in this position contributes to the development of real-time characterization system of antennas and arrays by programming wideband multiple-antenna transceivers and algorithms.

Our group is building an antenna testbed for characterizing mobile phone antenna array performance in real-time. The testbed requires accurate synchronization and control of multiple transceivers, as well as fast channel estimation and beamforming algorithms. The antenna testbed will be assembled in close collaboration with an expert on radio engineering and instrumentation. The chosen candidate is expected to accomplish the following tasks:
1.    Understanding how waveform transmission is realised in the current, besic testbed setup, especially the synchronization of multiple transceivers;
2.    Extending the testbed so that it performs real-time channel estimation and feedbacks from receiver to transmitter, in order to enable suitable signal combining at the receiver;
3.    Experimentally testing the operation of the testbed both in a laboratory cable-based-test and in an anechoic chamber over-the-air test; and finally
4.    Writing a scientific report about the realized testbed functionality.
The study will require close collaboration with a radio engineer who leads the design and implementation of the millimeter-wave over-the-air antenna testbed. The candidate is furthermore expected to communicate with an international wireless industry committed to the development of 5G mobile phones and their testing.

Research group
Associate Professor Katsuyuki Haneda leads the Antennas and propagation research group , which has been involved into several EU FP7 and Horizon 2020 projects about 5G-and-beyond physical layer studies and hence is known internationally to scientific and industrial research communities. Applications of the developed knowledge and experimental facilities about 5G-and-beyond cellular to industries are one of the key research missions of the group.

Requirements
Knowledge of physical layer wireless communication links, and experience in simulating wireless communications link performance (e.g. bit error rate) in equivalent baseband domain  through MATLAB is necessary. It is advantageous if the applicant has the following knowledge and skills:
•    Experience in programming software defined radio peripherals (USRPs) using e.g. LabView;
•    Knowledge of modern physical layer wireless communications including multiple-input multiple-output (MIMO) and orthogonal frequency division multiplexing (OFDM);
•    Experience of radio frequency instrumentation and measurements, e.g., antennas, microwave circuits and field tests.
Only students studying for a master’s degree can apply for this position. Applicants who already have a master’s degree are not eligible.

Salary and contract
This position will be filled up to six (6) months. A full-time work contract is granted if the candidate finishes all the other master level courses, while a part-time work is granted if the candidate needs to attend other courses in parallel to this employment. The salary follows the standard salary level of research assistants in the School of Electrical Engineering, based on the acquired study credits. We prefer that the work starts in September at the latest.

How to apply
Please submit your application through our recruiting system by using "Apply now!" link below and include the following documents in English:
•    Course transcripts of master’s study
•    Curriculum Vitae
Deadline for applications is May 31, 2021 but we will start reviewing candidates immediately upon receiving new application documents.
