MMSE Channel Estimation for Two-Port Demodulation Reference Signals in New Radio
Dejin Kong, Xiang-Gen Xia, Pei Liu +1
Two-port demodulation reference signals (DMRS) have been employed in new radio (NR) recently. In this paper, we firstly propose a minimum mean square error (MMSE) scheme with full…

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…
