Performance Evaluation of Mobile Target Sensing and Tracking Across Multiple Sensing Modes

Necati Kagan Erkek, Marco Di Renzo, Arman Shojaeifard +3

Moving extended-target sensing and tracking are studied in a beamformed PRS/OFDM ISAC framework. The target is modeled as a rigid cluster of scatterers whose Tx--target--Rx echoes…

On the Hulls of Group Codes

Xiheng Deng, Yuan Ren

Let be a finite field and a finte group with . By a group code in we mean a two-sided ideal in . We will prove a…

Spectral conditions for forbidden subgraphs in bipartite graphs

Yuan Ren, Jing Zhang, Zhiyuan Zhang

A graph is -free, if it contains no as a subgraph. A graph is said to be \emph{-minor free}, if it does not contain as a minor. In recent years, Nikiforov asked t…

Maximal Eisenstein ideals and cuspidal subgroups of modular Jacobian varieties

Yuan Ren

In this paper, we study the torsion subgroup of over the field generated by those points in the cuspidal group, where is an odd positive integer. We prove that, consid…

Arithmetic of Eisenstein quotients

Yuan Ren

In this paper, we will study the arithmetic of the Eisenstein part of the modular Jacobians. In the first section, we introduce some general preliminaries of the arithmetic theory…
