Joint Channel Estimation and Data Detection in Cell-Free Massive MU-MIMO Systems
Haochuan Song, Tom Goldstein, Xiaohu You +3
We propose a joint channel estimation and data detection (JED) algorithm for densely-populated cell-free massive multiuser (MU) multiple-input multiple-output (MIMO) systems, which…
Fundamental Rate-Memory Tradeoff for Coded Caching in Presence of User Inactivity
Jialing Liao, Olav Tirkkonen
Coded caching utilizes proper file subpacketization and coded delivery to make full use of the multicast opportunities in content delivery, to alleviate file transfer load in massi…
Exploiting Spatial Correlation for Pilot Reuse in Single-Cell mMTC
Lucas Ribeiro, Markus Leinonen, Hanan Al-Tous +2
As a key enabler for massive machine-type communications (mMTC), spatial multiplexing relies on massive multiple-input multiple-output (mMIMO) technology to serve the massive numbe…
Binary Subspace Chirps
Tefjol Pllaha, Olav Tirkkonen, Robert Calderbank
We describe in details the interplay between binary symplectic geometry and quantum computation, with the ultimate goal of constructing highly structured codebooks. The Binary Chir…
Decomposition of Clifford Gates
Tefjol Pllaha, Kalle Volanto, Olav Tirkkonen
In fault-tolerant quantum computation and quantum error-correction one is interested on Pauli matrices that commute with a circuit/unitary. We provide a fast algorithm that decompo…
