Joint Vehicle Tracking and RSU Selection for V2I Communications with Extended Kalman Filter
Jiho Song, Seong-Hwan Hyun, Jong-Ho Lee +2
We develop joint vehicle tracking and road side unit (RSU) selection algorithms suitable for vehicle-to-infrastructure (V2I) communications. We first design an analytical framework…
Adaptive Beam Design for V2I Communications using Vehicle Tracking with Extended Kalman Filter
Seong-Hwan Hyun, Jiho Song, Keunwoo Kim +2
Vehicle-to-everything communication system is a strong candidate for improving the driving experience and automotive safety by linking vehicles to wireless networks. To take advant…
Geometric Sequence Decomposition with -simplexes Transform
Woong-Hee Lee, Jong-Ho Lee, Ki Won Sung
This paper presents a computationally efficient technique for decomposing non-orthogonally superposed geometric sequences. The method, which is named as geometric sequence deco…
Limited Feedback Designs for Machine-type Communications Exploiting User Cooperation
Jiho Song, Byungju Lee, Song Noh +1
Multiuser multiple-input multiple-output (MIMO) systems are a prime candidate for use in massive connection density in machine-type communication (MTC) networks. One of the key cha…
Deep Learning Based NLOS Identification with Commodity WLAN Devices
Jeong-Sik Choi, Woong-Hee Lee, Jae-Hyun Lee +2
Identifying line-of-sight (LOS) and non-LOS (NLOS) channel conditions can improve the performance of many wireless applications, such as signal strength-based localization algorith…
Joint maximum likelihood estimation of carrier and sampling frequency offsets for OFDM systems
Y. H. Kim
In orthogonal-frequency division multiplexing (OFDM) systems, carrier and sampling frequency offsets (CFO and SFO, respectively) can destroy the orthogonality of the subcarriers an…
Full-Duplex Relay based on Zero-Forcing Beamforming
Jong-Ho Lee, Oh-Soon Shin
In this paper, we propose a full-duplex relay (FDR) based on a zero-forcing beamforming (ZFBF) for a multiuser MIMO relay system. The ZFBF is employed at the base station to suppre…
