Optimal energy efficiency in cell-free massive MIMO systems: A stochastic geometry approach
Papazafeiropoulos, Anastasios; Ngo, Hien Quoc; Kourtessis, Pandelis; Chatzinotas, Symeon; Senior, John M. (Institute of Electrical and Electronics Engineers (IEEE), 2020-10-08)The increasing demand for green wireless communications and the benefits of the promising cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems towards their optimal energy efficiency (EE) are the focal ... -
Performance of massive MIMO uplink with zero-forcing receivers under delayed channels
Papazafeiropoulos, Anastasios K.; Ngo, Hien Quoc; Ratnarajah, Tharmalingam (2017-04-01)In this paper, we analyze the performance of the uplink communication of massive multicell multiple-input multiple-output (MIMO) systems under the effects of pilot contamination and delayed channels because of terminal ...
