Scalable Cell-Free Massive MIMO with Multiple CPUs
Mathematics, 2022 In this paper, we consider the uplink of a scalable cell-free massive MIMO (CF-M-MIMO) system where user equipments (UEs) are served only by a subset of access points (APs).

Cell-Free Massive MIMO Versus Small Cells [PDF]
IEEE Transactions on Wireless Communications, 2017 A Cell-Free Massive MIMO (multiple-input multiple-output) system comprises a very large number of distributed access points (APs)which simultaneously serve a much smaller number of users over the same time/frequency resources based on directly measured channel characteristics. The APs and users have only one antenna each.

Cell-Free Massive MIMO With Multiple Active Eavesdroppers
IEEE Open Journal of the Communications SocietyThis paper investigates the secrecy performance of cell-free massive MIMO (CF-mMIMO) systems in the presence of active spoofing attacks by multiple eavesdroppers (Eves). Each Eve conducts a spoofing attack on a different legitimate user during the uplink
