Massive MIMO channel evaluation and modeling for 5G application
The PhD thesis here proposed is in the field of channel propagation modeling and wireless communication systems for 5G and beyond applications. In these networks, one of the possible solutions consists in using a high number of antennas in order to increase the datarate and address a high number of users.
This PhD thesis objective is to characterize and model the massive MIMO channel in S and Ka bands in order to evaluate the performance of future communication systems.
After an extensive study of the state of the art of 5G channel models for sub-6 GHz and mmwave, the PhD student will prepare the measurement campaigns by means of a 5G channel sounder. During this experimental phase an evolution of the measurement setup will be proposed, in order to use a high number of antennas and integrate innovative antenna array design from CEA-LETI. The measurement data will be used in order to statistically model the channel, eventually considering a spherical waves formalism. This model will be used to evaluate the intrinsic capacity of the massive MIMO channel and hybrid beamforming approaches.
The PhD student will be part of the Antenna, Propagation and Inductive Coupling Laboratory at CEA-LETI, in Grenoble (France). He/she will benefit of the state of the art facilities (channel sounders, emulator, OTA seutp, and electromagnetic simulator).
The PhD thesis will be carried out in collaboration with Université catholique de Louvain-la-Neuve (Belgium), under the supervision of Prof. Claude Oestges.
The student will eventually spend training periods in both institutes.
The position is open to outstanding students with Master of Science, “école d’ingénieur” or equivalent. The student should have specialization in the field of telecommunications, microwave and/or signal processing. The application must necessarily include a CV, cover letter and grades for the last two years of study.
