Active Reconfigurable Intelligent Surface Enhanced Spectrum Sensing for Cognitive Radio Networks

Autor: Ge, Jungang, Liang, Ying-Chang, Sun, Sumei, Zeng, Yonghong, Bai, Zhidong

In opportunistic cognitive radio networks, when the primary signal is very weak compared to the background noise, the secondary user requires long sensing time to achieve a reliable spectrum sensing performance, leading to little remaining time for t

Performance Analysis and Approximate Message Passing Detection of Orthogonal Time Sequency Multiplexing Modulation

Autor: Sui, Zeping, Yan, Shefeng, Zhang, Hongming, Sun, Sumei, Zeng, Yonghong, Yang, Lie-Liang, Hanzo, Lajos

In orthogonal time sequency multiplexing (OTSM) modulation, the information symbols are conveyed in the delay-sequency domain upon exploiting the inverse Walsh Hadamard transform (IWHT). It has been shown that OTSM is capable of attaining a bit error

Reflections, Trends and Prospects of the Development of Chinese Lesson Study in the Context of New Curriculum Reform

Autor: PENG Cheng, ZENG Yonghong

Publikováno v: Jiaoshi jiaoyu xuebao, Vol 11, Iss 4, Pp 114-122 (2024)

As an important approach to promoting teachers' professional development, Chinese lesson study provides consistent support for teachers to understand and implement the ideas of curriculum reform. However, looking back at the research content of Chine

Subband Random Sensing Grant Free Uplink for URLLC in Unlicensed Spectrum

Autor: Zeng, Yonghong, Wang, Yuhong, Sun, Sumei, Ma, Yugang

In this paper, we propose a novel scheme called subband random sensing (SRS) grant free uplink for ultra-reliable low-latency communication (URLLC) in unlicensed spectrum. The SRS grant free uplink creatively combines the subband sensing, user groupi
