Generalized Schalkwijk-Kailath Coding for Autoregressive Gaussian Channels
Jun Su, Guangyue Han, Shlomo Shamai
We propose a Gaussian random coding scheme for AR() Gaussian channels that generalizes the celebrated Schalkwijk-Kailath (SK) coding scheme. This constructive coding scheme, ter…
Learning under Quantization for High-Dimensional Linear Regression
Dechen Zhang, Junwei Su, Difan Zou
The use of low-bit quantization has emerged as an indispensable technique for enabling the efficient training of large-scale models. Despite its widespread empirical success, a rig…
Multi-Static Target Position Estimation and System Optimization for Cell-Free mMIMO-OTFS ISAC
Yifei Fan, Shaochuan Wu, Mingjun Sun +3
This paper investigates multi-static position estimation in cell-free massive multiple-input multiple-output (CF mMIMO) architectures, where orthogonal time frequency space (OTFS)…
Interference-Robust Broadband Rapidly-Varying MIMO Communications: A Knowledge-Data Dual Driven Framework
Jingjing Zhao, Jing Su, Kaiquan Cai +3
A novel time-efficient framework is proposed for improving the robustness of a broadband multiple-input multiple-output (MIMO) system against unknown interference under rapidly-var…
