Simulation of 5G NR cellular systems
In this dissertation, we evaluate the performance of 5G NR cellular systems operating in milliliter waves via numerical simulations, employing synthetic data and statistical models for the generation of representative communication channel parameters so as to reflect realistic propagation conditions in the 28 and 73GHz bands. The simulated scenarios consider a Massive MIMO model operating in TDD (time-division duplexing). All considered receivers use linear equalizers and beamformers whose calculations take into consideration intercellular interference and the use of estimated channel parameters. Simulation results show that intercellular interference is the main limiting factor of performance in such systems, which, however, can be mitigated by the use of cooperative equalization and beamforming algorithms.
