A GNN Approach for Cell-Free Massive MIMO
GLOBECOM 2022 - 2022 IEEE Global Communications Conference, 2022 Beyond 5G wireless technology Cell-Free Massive MIMO (CFmMIMO) downlink relies on carefully designed precoders and power control to attain uniformly high rate coverage. Many such power control problems can be calculated via second order cone programming (SOCP). In practice, several order of magnitude faster numerical procedure is required because power

Cell-Free Massive MIMO Meets OTFS Modulation [PDF]
IEEE Transactions on Communications, 2022 We provide the first-ever performance evaluation of orthogonal time frequency space (OTFS) modulation in cell-free massive multiple-input multiple-output (MIMO) systems. To investigate trade-off between performance and overhead, we apply embedded pilot-aided and superimposed pilot-based channel estimation methods.

Foundations of User-Centric Cell-Free Massive MIMO [PDF]
Foundations and Trends® in Signal Processing, 2021 Imagine a coverage area where each mobile device is communicating with a preferred set of wireless access points (among many) that are selected based on its needs and cooperate to jointly serve it, instead of creating autonomous cells. This effectively leads to a user-centric post-cellular network architecture, which can resolve many of the ...

Cell-Free Massive MIMO with Limited Backhaul [PDF]
2018 IEEE International Conference on Communications (ICC), 2018 We consider a cell-free Massive multiple-input multiple-output (MIMO) system and investigate the system performance for the case when the quantized version of the estimated channel and the quantized received signal are available at the central processing unit (CPU), and the case when only the quantized version of the combined signal with maximum ratio ...

A Review on Cell-Free Massive MIMO Systems
Electronics, 2023 Cell-free massive multiple-input multiple-output (CF mMIMO) can be considered as a potential physical layer technology for future wireless networks since it can benefit from all the advantages of distributed antenna systems (DASs) and network MIMOs, such as macro-diversity gain, high channel capacity, and link reliability.

Coverage Probability of Cell-Free Massive MIMO Systems [PDF]
2020 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2020 Despite that ongoing and future networks become denser and increasingly irregular, prior works in the area of cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems relied on the strong assumption of uniformly distributed access points (APs).

Pilot Power Control for Cell-Free Massive MIMO [PDF]
IEEE Transactions on Vehicular Technology, 2018 In this correspondence paper, we consider a cell-free massive Multiple-Input Multiple-Output (MIMO) system where access points (APs) serve a much smaller number of users under the time-division duplex operation. The APs first estimate the channels via the uplink training phase.
