Ultrareliable and Low-Latency Communication Techniques for Tactile Internet Services
Kwang Soon Kim, Dong Ku Kim, Chan-Byoung Chae +9
This paper presents novel ultrareliable and low-latency communication (URLLC) techniques for URLLC services, such as Tactile Internet services. Among typical use-cases of URLLC ser…
Cramer-Rao Lower Bound for DoA Estimation with RF Lens-Embedded Antenna Array
Jae-Nam Shim, Hongseok Park, GeeYong Suk +2
In this paper, we consider the Cramer-Rao lower bound (CRLB) for estimation of a lens-embedded antenna array with deterministic parameters. Unlike CRLB of uniform linear array (ULA…
Compact Full Duplex MIMO Radios in D2D Underlaid Cellular Networks: From System Design to Prototype Results

This paper considers the implementation and application possibilities of a compact full duplex multiple-input multiple-output (MIMO) architecture where direct communication exists…
Nonlinear Self-Interference Cancellation for Full-Duplex Radios: From Link- and System-Level Performance Perspectives
Min Soo Sim, MinKeun Chung, Dongkyu Kim +3
One of the promising technologies for LTE Evolution is full-duplex radio, an innovation is expected to double the spectral efficiency. To realize full-duplex in practice, the main…
Degrees of Freedom of Full-Duplex Cellular Networks with Reconfigurable Antennas at Base Station
Minho Yang, Sang-Woon Jeon, Dong Ku Kim
Full-duplex (FD) cellular networks are considered in which a FD base station (BS) simultaneously supports a set of half-duplex (HD) downlink (DL) users and a set of HD uplink (UL)…
A Desired PAR-Achieving Precoder Design for Multi-User MIMO OFDM based on Concentration of Measure
Hyun-Su Cha, Dong Ku Kim
For multi-user multiple-input and multiple-output (MIMO) wireless communications in orthogonal frequency di- vision multiplexing systems, we propose a MIMO precoding scheme providi…
Prototyping Real-Time Full Duplex Radios

The Feasibility of Interference Alignment for Reverse TDD Systems in MIMO Cellular Networks
Kiyeon Kim, Sang-Woon Jeon, Janghoon Yang +1
The feasibility conditions of interference alignment (IA) are analyzed for reverse TDD systems, i.e., one cell operates as downlink (DL) but the other cell operates as uplink (UL).…
Linear Degrees of Freedom of MIMO Broadcast Channels with Reconfigurable Antennas in the Absence of CSIT
Minho Yang, Sang-Woon Jeon, Dong Ku Kim
The K-user multiple-input and multiple-output (MIMO) broadcast channel (BC) with no channel state information at the transmitter (CSIT) is considered, where each receiver is assume…
Generalized Distributed Compressive Sensing
Jeonghun Park, Seunggye Hwang, Janghoon Yang +1
Distributed Compressive Sensing (DCS) improves the signal recovery performance of multi signal ensembles by exploiting both intra- and inter-signal correlation and sparsity structu…
Feedback-Topology Designs for Interference Alignment in MIMO Interference Channels
Sungyoon Cho, Kaibin Huang, Dongku Kim +4
Interference alignment (IA) is a joint-transmission technique that achieves the capacity of the interference channel for high signal-to-noise ratios (SNRs). Most prior work on IA i…
