How to interconnect for Massive MIMO Self-Calibration?
Fuqian Yang, Hanyu Zhu, Cong Shen +2
In time-division duplexing (TDD) systems, massive multiple-input multiple-output (MIMO) relies on the channel reciprocity to obtain the downlink (DL) channel state information (CSI…
Regional Multi-Armed Bandits
Zhiyang Wang, Ruida Zhou, Cong Shen
We consider a variant of the classic multi-armed bandit problem where the expected reward of each arm is a function of an unknown parameter. The arms are divided into different gro…
New Results on Multilevel Diversity Coding with Secure Regeneration
Shuo Shao, Tie Liu, Chao Tian +1
The problem of multilevel diversity coding with secure regeneration is revisited. Under the assumption that the eavesdropper can access the repair data for all compromised storage…
Multilevel Diversity Coding with Secure Regeneration: Separate Coding Achieves the MBR Point
Shuo Shao, Tie Liu, Chao Tian +1
The problem of multilevel diversity coding with secure regeneration (MDC-SR) is considered, which includes the problems of multilevel diversity coding with regeneration (MDC-R) and…

A Scalable Framework for CSI Feedback in FDD Massive MIMO via DL Path Aligning
Xiliang Luo, Penghao Cai, Xiaoyu Zhang +2
Unlike the time-division duplexing (TDD) systems, the downlink (DL) and uplink (UL) channels are not reciprocal anymore in the case of frequency-division duplexing (FDD). However,…
