支持向量机在射频功率器件建模中的应用研究

In the modern electronic communications technology，large-signal conditions, RF power device modeling occupies an important position. Our goal is able to acquire a case of high model accuracy in a short time and less cost. support vector machine algorithm is applied to model the RF power devices in this paper, we improve the support vector machine and increase knowledge of the scattering function to establish the model of device. We Compare the different results of original and modified support vector machine.It is obtained that the modified support vector machine is better in the noise inhibition, and improve the accuracy of the model up to 7.46% at the Maximum point.
