A Left-Null-Space-Based Massive Access Method for Cell-Free Massive MIMO IoT Systems

open access: yesSensors, 2023
Cell-free massive multiple-input multiple-output (MIMO) is a promising technology for the Internet of Things (IoT) because it can increase connectivity and provide considerable energy efficiency (EE) and spectral efficiency (SE).

Near-Optimal Massively Parallel Graph Connectivity [PDF]

open access: yes2019 IEEE 60th Annual Symposium on Foundations of Computer Science (FOCS), 2019
Identifying the connected components of a graph, apart from being a fundamental problem with countless applications, is a key primitive for many other algorithms. In this paper, we consider this problem in parallel settings. Particularly, we focus on the Massively Parallel Computations (MPC) model, which is the standard theoretical model for modern ...

Optimal Deterministic Massively Parallel Connectivity on Forests

open access: yes, 2023
We show fast deterministic algorithms for fundamental problems on forests in the challenging low-space regime of the well-known Massive Parallel Computation (MPC) model. A recent breakthrough result by Coy and Czumaj [STOC'22] shows that, in this setting, it is possible to deterministically identify connected components on graphs in $O(\log D + \log ...
