Multi-Domain Iterative Detection for Massive Connectivity in LEO Satellite Networks
Xinhua Liu, Yueqing Wang, Keke Ying +7
Grant-Free (GF) random access is promising for low Earth orbit satellite Internet due to its reduced access latency. However, existing schemes suffer from poor performance in massi…
Performance Analysis of Fronthaul Compression in Massive MIMO Receiver
Roman Bychkov, Andrey Dergachev, Alexander Osinsky +2
Future generations of cellular systems presume to use an extremely high number of antennas to enable mm waves. Increasing the number of antennas requires a growth in connections be…
Probabilistic Examination of Least Squares Error in Low-bitwidth Cholesky Decomposition
Alexander Osinsky, Roman Bychkov, Mikhail Trefilov +2
In this paper, we propose a new approach to justify a round-off error impact on the accuracy of the linear least squares (LS) solution using Cholesky decomposition. This decomposit…
