Tensor Decomposition Bounds for TBM-Based Massive Access
Alexis Decurninge, Ingmar Land, Maxime Guillaud
Tensor-based modulation (TBM) has been proposed in the context of unsourced random access for massive uplink communication. In this modulation, transmitters encode data as rank-1 t…
Tensor-Based Modulation for Unsourced Massive Random Access
Alexis Decurninge, Ingmar Land, Maxime Guillaud
We introduce a modulation for unsourced massive random access whereby the transmitted symbols are rank-1 tensors constructed from Grassmannian sub-constellations. The use of a low-…
Joint Constellation Design for the Two-User Non-Coherent Multiple-Access Channel
Khac-Hoang Ngo, Sheng Yang, Maxime Guillaud +1
We consider the joint constellation design problem for the two-user non-coherent multiple-access channel (MAC). Based on an analysis on the non-coherent maximum-likelihood (ML) det…
Multi-User Detection Based on Expectation Propagation for the Non-Coherent SIMO Multiple Access Channel
Khac-Hoang Ngo, Maxime Guillaud, Alexis Decurninge +2
We consider the non-coherent single-input multiple-output (SIMO) multiple access channel with general signaling under spatially correlated Rayleigh block fading. We propose a novel…
Cube-Split: A Structured Grassmannian Constellation for Non-Coherent SIMO Communications
Khac-Hoang Ngo, Alexis Decurninge, Maxime Guillaud +1
In this paper, we propose a practical structured constellation for non-coherent communication with a single transmit antenna over Rayleigh flat and block fading channel without ins…
Covariance-Aided CSI Acquisition with Non-Orthogonal Pilots in Massive MIMO: A Large-System Performance Analysis
Alexis Decurninge, Luis G. Ordóñez, Maxime Guillaud
Massive multiple-input multiple-output (MIMO) systems use antenna arrays with a large number of antenna elements to serve many different users simultaneously. The large number of a…
