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.

Uplink Performance of Cell-Free Massive MIMO with Access Point Selections [PDF]
EAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2018 Cell-free massive multiple-input multiple-output (MIMO), in which a massive number of access points (APs) distributed over a large area serve a smaller number of users in the same time and frequency resources, inherits advantages from conventional ...

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 ...

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 ...
