Study and mitigation techniques of RF impairments for beyond 5G multi-carrier waveforms

Abstract : Fundamental research towards beyond 5G cellular networks is ongoing and the vision of 2020 and beyond includes a significant amount use cases considering a massive number of devices with a wide range of characteristics and demands. On the one hand, the good spectral efficiency gives more capacity for the transmission while on the other hand, building compact and low-cost flexible and high-quality radio equipment is a very challenging task. The context of this thesis is the study of massive MIMO techniques with the presence of radio frequency (RF) imperfections, in particular, the non-linear (NL) power amplifiers (PA). The large number of PAs equipped in the base station (BS) creates various constraints which lead to strong degradation of the transmission quality both in the band and out of band. On the other hand, 5G standardization introduced the concept of different numerologies together with the massive MIMO technique. The influence of the different numerologies used by the different users will also be studied in this thesis.
