Beam-Squint-Aided Hierarchical Sensing for Integrated Sensing and Communications with Uniform Planar Arrays
Jaehong Jo, Jihun Park, Yo-Seb Jeon +1
In this paper, we propose a novel hierarchical sensing framework for wideband integrated sensing and communications with uniform planar arrays (UPAs). Leveraging the beam-squint ef…
Robust Nonlinear Transform Coding: A Framework for Generalizable Joint Source-Channel Coding
Jihun Park, Junyong Shin, Jinsung Park +1
This paper proposes robust nonlinear transform coding (Robust-NTC), a generalizable digital joint source-channel coding (JSCC) framework that couples variational latent modeling wi…
Rate-Adaptive Semantic Communication via Multi-Stage Vector Quantization
Jinsung Park, Junyong Shin, Yongjeong Oh +2
This paper proposes a novel framework for rate-adaptive semantic communication based on multi-stage vector quantization (VQ), termed \textit{MSVQ-SC}. Unlike conventional single-st…
Importance-Aware Semantic Communication in MIMO-OFDM Systems Using Vision Transformer
Joohyuk Park, Yongjeong Oh, Jihun Park +1
This paper presents a novel importance-aware quantization, subcarrier mapping, and power allocation (IA-QSMPA) framework for semantic communication in multiple-input multiple-outpu…
Prior-Aware Robust Beam Alignment for Low-SNR Millimeter-Wave Communications
Jihun Park, Yongjeong Oh, Jaewon Yun +2
This paper presents a robust beam alignment technique for millimeter-wave communications in low signal-to-noise ratio (SNR) environments. The core strategy of our technique is to r…
