Time-Frequency Analysis based Deep Interference Classification for Frequency Hopping System
Changzhi Xu, Jingya Ren, Wanxin Yu +4
It is known that, interference classification plays an important role in protecting the authorized communication system and avoiding its performance degradation in the hostile envi…
Two New Kinds of Interference Alignment Schemes for Cellular K-user MIMO Downlink Networks
Jingfu Li, Wenjiang Feng, F. Richard Yu +1
It is known that interference alignment (IA) plays an important role in improving the degree of freedom (DoF) of multi-input and multi-output (MIMO) systems. However, most of the t…
Joint Transmit Precoding and Reflect Beamforming Design for IRS-Assisted MIMO Cognitive Radio Systems
Weiheng Jiang, Yu Zhang, Jun Zhao +2
Cognitive radio (CR) is an effective solution to improve the spectral efficiency (SE) of wireless communications by allowing the secondary users (SUs) to share spectrum with primar…
Multi-Agent Reinforcement Learning for Joint Cooperative Spectrum Sensing and Channel Access in Cognitive UAV Networks
Weiheng Jiang, Wanxin Yu, Wenbo Wang +1
This paper studies the problem of distributed spectrum/channel access for cognitive radio-enabled unmanned aerial vehicles (CUAVs) that overlay upon primary channels. Under the fra…
