Cell-free Massive MIMO with Short Packets [PDF]
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2021 In this paper, we adapt to cell-free Massive MIMO (multiple-input multiple-output) the finite-blocklength framework introduced by Östman et al. (2020) for the characterization of the packet error probability achievable with Massive MIMO, in the ultra ...
