DropBlock based bimodal hybrid neural network for wireless communication modulation recognition by Yan GAO, Jian SHI, Shengyu MA, Bolin MA, Guangxue YUE

“…As an intermediate step of signal detection and demodulation, automatic modulation recognition played a momentous role in wireless communication system.Aiming at the low recognition accuracy of existing automatic modulation recognition methods, a bimodal hybrid neural network (BHNN) was proposed, which utilized complementary gain information contained in multiple modes to enrich feature dimensions.The improved residual network was connected in parallel with the bidirectional gated loop unit to construct a bimodal hybrid neural network model, and the spatial and temporal features of the signal were extracted respectively.The DropBlock regularization algorithm was introduced to effectively suppress the influence of over fitting, gradient disappearance and gradient explosion on the recognition accuracy in the process of network training.Using bimodal data input, the spatial and temporal characteristics of signals were fully utilized, and the network depth was reduced through parallel connection.The model convergence was accelerated, and the recognition accuracy of modulated signals was improved.In order to verify the effectiveness of the model, two public datasets were used to simulate the model.The results show that BHNN has high recognition accuracy and strong stability on the two datasets, and the recognition accuracy can reach 89% and 93.63% respectively under high signal-to-noise ratio.…”

Water Chemistry and Nitrogen and Oxygen Isotope Techniques for Tracing Nitrate Sources and Transformation Processes in Ionic Rare Earth Mining Areas by GUO Qiuyan, ZHANG Qiuying, LI Zhao, LI Fadong, WANG Fan

“…To identify the source,migration and transformation processes,and pollution contribution of nitrate in the water body of ionic rare earth mining areas,this paper determined the anions and nitrate nitrogen-oxygen isotopes of surface and groundwater samples by taking Longnan County as the study area.The results show that the water chemistry type in Longnan County is basically dominated by HCO₃·SO₄-Ca,and the nitrogen-containing compounds are dominated by nitrate.The characteristic plots of the values of δ¹⁵N-NO^-₃ and δ¹⁸O-NO^-₃ combined with the relationship between NO^-₃/Cl^- molar concentration ratios and Cl^- concentrations show that the nitrate concentrations in the Longnan County are mainly influenced by ammonium nitrogen fertilizer,soil nitrogen,manure and mine drainage and that the main process of nitrate transformation is nitrification,with no significant denitrification reactions.The results of the MixSIAR model also show that the nitrate in surface water and groundwater mainly comes from mine drainage,soil nitrogen and manure.…”

Compound Fault Feature Extraction of Gearbox based on Improve Variational Mode Decomposition by Chai Huili, Ye Meitao, Wang Zhijian

“…In the practical condition,the fault signal of gearbox often contain multiple fault information,but the weak fault signal belongs to weak signal compared with strong fault signal and noise,therefore,the extraction of weak fault signal in complex fault is always a difficult point in rotating machinery fault diagnosis.Based on the problems above,considering that MED（ Minimum Entropy Deconvolution） has strong reduction performance of noise,the intrinsic mode function decomposed by VMD（ Variational Mode Decomposition） is distorted in strong noise environment. …”
