Training Signal Design for Sparse Channel Estimation in Intelligent Reflecting Surface-Assisted Millimeter-Wave Communication
Song Noh, Heejung Yu, Youngchul Sung
In this paper, the problem of training signal design for intelligent reflecting surface (IRS)-assisted millimeter-wave (mmWave) communication under a sparse channel model is consid…
Tomlinson-Harashima Precoding-Aided Multi-Antenna Non-Orthogonal Multiple Access
Jungho So, Youngchul Sung, Yong H. Lee
In this paper, Tomlinson-Harashima Precoding (THP) is considered for multi-user multiple-input single-output (MU-MISO) non-orthogonal multiple access (NOMA) donwlink. Under the hie…
A High-Diversity Transceiver Design for MISO Broadcast Channels
Junyeong Seo, Youngchul Sung, Hamid Jafarkhani
In this paper, the outage behavior and diversity order of the mixture transceiver architecture for multiple-input single-output broadcast channels are analyzed. The mixture scheme…
Beam Design and User Scheduling for Non-Orthogonal Multiple Access with Multiple Antennas Based on Pareto-Optimality
Junyeong Seo, Youngchul Sung
In this paper, an efficient transmit beam design and user scheduling method is proposed for multi-user (MU) multiple-input single-output (MISO) non-orthogonal multiple access (NOMA…
Filter Design for Generalized Frequency-Division Multiplexing
Seungyul Han, Youngchul Sung, Yong H. Lee
In this paper, optimal filter design for generalized frequency-division multiplexing (GFDM) is considered under two design criteria: rate maximization and out-of-band (OOB) emissio…
Enhancing Non-Orthogonal Multiple Access By Forming Relaying Broadcast Channels
Jungho So, Youngchul Sung
In this paper, using relaying broadcast channels (RBCs) as component channels for non-orthogonal multiple access (NOMA) is proposed to enhance the performance of NOMA in single-inp…
