Flatten: Video Action Recognition is an Image Classification task

no code implementations17 Aug 2024 Junlin Chen, Chengcheng Xu, Yangfan Xu, Jian Yang, Jun Li, Zhiping Shi

In recent years, video action recognition, as a fundamental task in the field of video understanding, has been deeply explored by numerous researchers. Most traditional video action recognition methods typically involve converting videos into three-dimensional data that encapsulates both spatial and temporal information, subsequently leveraging prevalent image understanding models to model and analyze these data.

Rate-Splitting Multiple Access for Multi-Antenna Joint Radar and Communications

no code implementations14 Mar 2021 Chengcheng Xu, Bruno Clerckx, Shiwa Chen, Yijie Mao, Jianyun Zhang

In this work, we propose a powerful and unified multi-antenna DFRC transmission framework, where an additional radar sequence is transmitted apart from communication streams to enhance radar beampattern matching capability, and Rate-Splitting Multiple Access (RSMA) is adopted to better manage the interference.

Multi-Antenna Joint Radar and Communications: Precoder Optimization and Weighted Sum-Rate vs Probing Power Tradeoff

no code implementations28 Jan 2021 Chengcheng Xu, Bruno Clerckx, Jianyun Zhang

The tradeoffs between WSR and probing power at target are compared among both proposed transmissions and two practically simpler dual-function implementations i. e., time division and frequency division.

Signal Shaping for Non-Uniform Beamspace Modulated mmWave Hybrid MIMO Communications

no code implementations23 Jun 2020 Shuaishuai Guo, Haixia Zhang, Peng Zhang, Shuping Zhang, Chengcheng Xu, Mohamed-Slim Alouini

Specifically, we firstly propose a joint optimization based signal shaping (JOSS) approach, in which the symbol vector sets used for all analog precoder activation states are jointly optimized by solving a series of quadratically constrained quadratic programming (QCQP) problems.
