LDPC Code Design for Distributed Storage: Balancing Repair Bandwidth, Reliability and Storage Overhead
Hyegyeong Park, Dongwon Lee, Jaekyun Moon
Distributed storage systems suffer from significant repair traffic generated due to frequent storage node failures. This paper shows that properly designed low-density parity-check…
On Reusing Pilots Among Interfering Cells in Massive MIMO
Jy-yong Sohn, Sung Whan Yoon, Jaekyun Moon
Pilot contamination, caused by the reuse of pilots among interfering cells, remains as a significant obstacle that limits the performance of massive multi-input multi-output antenn…
NOMA in Distributed Antenna System for Max-Min Fairness and Max-Sum-Rate
Dong-Jun Han, Minseok Choi, Jaekyun Moon
Distributed antenna system (DAS) has been deployed for over a decade. DAS has advantages in capacity especially for the cell edge users, in both single-cell and multi-cell environm…
Pilot Reuse Strategy Maximizing the Weighted-Sum-Rate in Massive MIMO Systems
Jy-yong Sohn, Sung Whan Yoon, Jaekyun Moon
Pilot reuse in multi-cell massive multi-input multi-output (MIMO) system is investigated where user groups with different priorities exist. Recent investigation on pilot reuse has…
Secure Clustered Distributed Storage Against Eavesdroppers
Beongjun Choi, Jy-yong Sohn, Sung Whan Yoon +1
This paper considers the security issue of practical distributed storage systems (DSSs) which consist of multiple clusters of storage nodes. Noticing that actual storage nodes cons…
