Machine Learning Enabled Preamble Collision Resolution in Distributed Massive MIMO
Jie Ding, Daiming Qu, Pei Liu +1
Preamble collision is a bottleneck that impairs the performance of random access (RA) user equipment (UE) in grant-free RA (GFRA). In this paper, by leveraging distributed massive…

Optimal Preamble Length for Spectral Efficiency in Grant-Free RA with Massive MIMO
Jie Ding, Daiming Qu, Hao Jiang
Grant-free random access (RA) with massive MIMO is a promising RA technique for massive access with low signaling overhead. In the grant-free RA with massive MIMO, preamble length…

Smoothed SVD-based Beamforming for FBMC/OQAM Systems Based on Frequency Spreading
Yu Qiu, Daiming Qu, Da Chen +1
The combination of singular value decomposition (SVD)-based beamforming and filter bank multicarrier with offset quadrature amplitude modulation (FBMC/OQAM) has not been successful…
