- Improved WEIghted Covariance-based Detector for Spectrum Sensing in RaylEIgh Fading Channel
- IEEE WIRELESS COMMUNICATIONS LETTERSLai, Huadong Liu, Mingxing Xu, Jinqiang Luo, Peng Chen, Changrun Xu, Weichao 出版年：2024
- In this letter, we propose an improved wEIghted covariance based detector (IWCD) for spatially correlated time-varying RaylEIgh fading channel. The proposed method uses adaptive wEIghts that are tailored to the dynamic n...
- Kendall's Tau based Spectrum Sensing for Cognitive Radio in the Presence of Laplace Noise
- IEEE SIGNAL PROCESSING LETTERSHuang, Yongjian Lai, Huadong Dai, Jisheng Xu, Weichao 出版年：2024
- In the presence of non-Gaussian noise, traditional spectrum sensing techniques optimized for Gaussian noise may experience significant performance degradation. To address this challenge, this paper employs Kendall's tau ...
- LMPIT-based Spectrum Sensing for Non-Circular Signals in Multi-Antenna Cognitive Radios
- IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONSLai, Huadong Luo, Peng Liu, Mingxin Xu, Jinqiang 出版年：2025
- This paper addresses a robust spectrum sensing scheme for non-circular (NC) primary signals within the framework of locally most power invariant test (LMPIT). The proposed method is referred as the NCJT detector because ...
- GLRT-based Spectrum Sensing for Non-Circular Signals in Cognitive Radios With Multiple Antennas
- IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGYLai, Huadong Liu, Mingxing Xu, Jinqiang Luo, Peng Xu, Weichao 出版年：2025
- Traditional spectrum sensing schemes devised under the presumption of circular signals may suffer from performance deterioration when non-circular (NC) signals are present. To circumvent this drawback, this paper devises...
- 基于广义似然比的非圆信号频谱感知方法
- 《电子科技大学学报》赖华东 罗朋 徐今强 刘洺辛 出版年：2025
- 传统的频谱感知方案通常假设信号为圆信号,在非圆信号的信道环境下存在一定程度的性能损失。针对这一问题,提出了一种基于非圆信号的频谱感知方法。利用非圆信号的补偿协方差不为零的特征,在广义似然比的框架下推导了检验统计量。该方法...
