| 1 | Joint Spectrum Sensing Based on Variance and Correlation Analysis显示文摘In this paper, a novel detection criterion is proposed to decide whether primary user(PU) exists based on joint analysis of the variance and correlation for observation signal,considering a correlation within the observed signal. Simultaneously, the corresponding detection thresholds are also designed. Simulation experiments verify the proposed method suits for the observation signal in Additive White Gaussian Noise(AWGN), Rayleigh,Rician channel and the detection performance is improved greatly. | Junsheng Mu Xiaojun Jing Hai Huang Ning Gao | 2017 | China Communications2017，14，10： | 1 |
| 2 | Cooperative Spectrum Sensing Based on Centralized Double Threshold in MCN显示文摘Cooperative spectrum sensing appears popular currently due to its ability to solve the issue of hidden terminal and improve detection performance in Cognitive Radio Networks. Meanwhile, double threshold based energy detector has attracted much attention for its low computational complexity and superior performance. Motivated by this, a cooperative spectrum sensing scheme is proposed in this paper based on centralized double threshold in the maritime communication networks(MCN), where the energy value of received signal in each cognitive node is forwarded to the fusion center for final decision based on double thresholds. Additionally, the proposed scheme is further optimized for the decisions that the energy is within the scope of maximum threshold and minimum threshold. Simulation experiments verify the performance of the proposed method. | Hai Huang Junsheng Mu Xiaojun Jing | 2020 | China Communications2020，17，5： | 0 |
| 3 | A Blind Spectrum Sensing Based on Low-Rank and Sparse Matrix Decomposition显示文摘As a crucial component in Cognitive Radio(CR) networks, spectrum sensing has been attracting lots of attention. Some conventional methods for spectrum sensing are sensitive to uncertain signal and noise, its applicability is limited thereof. In this paper, a novel blind spectrum sensing method is proposed, where low-rank and sparse matrix decomposition is applied to the observation signal of a CR in the frequency domain. Then the ratio of the energy of the sparse part and the received signal in the time domain is considered as the criterion to decide whether the radio frequency band is idle by means of a comparison with a predefined threshold. The proposed method is independent of prior knowledge of signal and white noise, and has a better detection performance. Simulation experiments verify the performance of the proposed method in additive white Gaussian noise(AWGN), Rayleighand Rician channels. | Junsheng Mu Xiaojun Jing Hai Huang Ning Gao | 2018 | China Communications2018，15，8： | 0 |
| 4 | Mutual Information Maximization via Joint Power Allocation in Integrated Sensing and Communications System显示文摘In this paper, we focus on the power allocation of Integrated Sensing and Communication(ISAC) with orthogonal frequency division multiplexing(OFDM) waveform. In order to improve the spectrum utilization efficiency in ISAC, we propose a design scheme based on spectrum sharing, that is,to maximize the mutual information(MI) of radar sensing while ensuring certain communication rate and transmission power constraints. In the proposed scheme, three cases are considered for the scattering off the target due to the communication signals,as negligible signal, beneficial signal, and interference signal to radar sensing, respectively, thus requiring three power allocation schemes. However,the corresponding power allocation schemes are nonconvex and their closed-form solutions are unavailable as a consequence. Motivated by this, alternating optimization(AO), sequence convex programming(SCP) and Lagrange multiplier are individually combined for three suboptimal solutions corresponding with three power allocation schemes. By combining the three algorithms, we transform the non-convex problem which is difficult to deal with into a convex problem which is easy to solve and obtain the suboptimal solution of the corresponding optimization problem. Numerical results show that, compared with the allocation results of the existing algorithms, the proposed joint design algorithm significantly improves the radar performance. | Jia Zhu Junsheng Mu Yuanhao Cui Xiaojun Jing | 2024 | China Communications2024，21，2： | 0 |

| 9 | Spatiotemporal variation of cyanobacterial harmful algal blooms in China based on literature and media information显示文摘Cyanobacterial harmful algal blooms(CyanoHABs)in inland waters are now among the most pressing environmental issues worldwide,especially in China.Satellite remote sensing has limitations in monitoring CyanoHABs in small water bodies due to spatial and temporal resolution limitations.While literature and news media have the potential to supplement satellite remote sensing in monitoring CyanoHABs,they have currently not received sufficient attention.In this study,we combined information on the distributions of CyanoHABs from literature and media for the first time to comprehensively assess the spatiotemporal variation in CyanoHABs in China.We collected,cleaned,validated,and organized data from literature and media on CyanoHABs in China,resulting in the establishment of a comprehensive database on CyanoHABs in China's inland waters(ChinaCyanoDB)covering 198 water bodies,525 records for 1950-2021.The majority of water bodies with CyanoHABs(CyanoWaters)are located in the eastern China,mainly concentrated in the middle and lower Yangtze region,with a clear upward trend in their number over the last four decades.The ChinaCyanoDB and analytical results can provide valuable data support for monitoring and managing CyanoHABs in China while the database construction method may also be applied to other countries and regions. | Yichen Du Chen Wang Mengqiu Wang Huan Zhao Kai Yan Yunchang Mu Wenzhi Zhang Fangfang Zhang Shenglei Wanga Junsheng Li | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 10 | Cardiac surgical operation after renal transplantation显示文摘Several studies reported the impact of cardiac surgical operation on morbidity and mortality in renal transplant recipients as well as on renal graft function and safety and effect of immunosuppressant medication.1-3 However,few data are available about the risk and immunosuppressant medication in patients who undergo cardiac surgical operation after successful renal transplantation,especially in patients who underwent offpump coronary artery bypass grafting (CABG) with previous renal transplantation.This research provides important insights into the immunosuppressive management of a patient requiring valve replacement or CABG after renal transplantation during the perioperative period. | Mu Junsheng Zhou Fan Li Xianshuai Zhang Jianqun Bo Ping | 2014 | Chinese Medical Journal2014，，10： | 0 |
