In this study, we derive a new closed-form expression for the downlink (DL) SE of a cell-free Massive MIMO system with multi-antenna APs and fpZF precoding, under imperfect CSI and pilot contamination. The analysis also includes max-min fairness DL power optimization. Numerical results show ...
massive MIMO, and user-based joint transmission coordinated multi-point (JT-CoMP) [26] to deal with inter-cell interference [27]. Additionally, CF-mMIMO provides massive macro-diversity to mitigate
It can be noticed that this mathematical analysis does not include cross-tier interference at the base station into account; thus, this is assessed as a femtocell stage study. Fig. 5 illustrates the trade-off between EE and SE of the cooperative cognitive VAA networks with corresponding MIMO ...

In summary, both cell densification and mMIMO might be well suited for increasing the peak and average rates in future cellular networks. Still, the user-experienced data rates will remain modest due to inter-cell interference and large SNR variations. 1.1. Cell-free mMIMO: the best of two ...
