A measurement system combining vector corrected waveform measurements with active harmonic load-pull extends, for the first time, real-time experimental waveform engineering up to the 30W power level. This novel harmonic load-pull approach is demonstrated on a 4W LDMOS device. A 20% increase in maximum output power to 4.7Watts without degrading gain and efficiency was realized.
With the continuous innovation of computer technology, it can solve the problems of low accuracy, non-intelligence, and inability to process complex samples in the sales forecasting methods of industrial supply chains. This paper proposes a sales forecasting method for the industrial supply chain based on the Gaussian mixture model. By analyzing the characteristics of the original sales data of the industrial supply chain, the eigenvalue correlation ranking vector is generated. Then predict the parameters such as the number of clusters in the Gaussian mixture model. By comparing the accuracy of the prediction results, the recall rate and the Fvalue, the eigenvalues, and the number of clusters that can achieve better prediction results are determined. This paper compares the Gaussian mixture model with the artificial neural network model and the convolutional neural network model on the original sales data set of the same industrial supply chain. The experimental results show that, compared with the artificial neural network model and the convolutional neural network model, the method has better performance in all three indicators, and can better predict sales transactions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
