Abstract: The present disclosure provides a device and method of generating a nonlinear waveform signal dissipating low power and operating at a high speed. The device includes: a digital preprocessing unit configured to quantize an effective input signal to generate a linear data signal and a residual signal that is a difference between the effective input signal and the linear data signal; a nonlinear digital-to-analog conversion circuit (DAC) having a nonlinear relationship between an input and an output and configured to convert the linear data signal into a first analog signal; a linear interpolation DAC configured to convert the residual signal into a second analog signal to enable a generation of a converted analog signal by an addition of the second analog signal to the first analog signal; and an output circuit configured to output the converted analog signal as a nonlinear waveform signal.

Abstract: The present invention relates to a technique in which demand prediction of resources of virtual network functions (VNFs) that provide a core technology in a network virtualization environment is performed using machine learning technology. In the present invention, in order to predict VNF resource information, not only are the resources of the VNFs as data but also information of surrounding VNFs that are directly or indirectly related are used, and prediction is possible even in a dynamically changed network environment. In addition, service function chain (SFC) data among various pieces of network information is used to reduce a time required for machine learning according to a size of an entire network.

Abstract: A touch sensor-antenna module includes a touch sensor electrode layer including a plurality of sensing electrodes and traces electrically connected to the sensing electrodes, and an antenna electrode layer disposed over the touch sensor electrode layer or under the touch sensor electrode layer. The antenna electrode layer includes an antenna pattern that does not overlap the traces in a planar view. An electrical interference from the traces may be reduced to improve an antenna signal property.

Abstract: An antenna device according to an embodiment of the present invention includes a dielectric layer, and an antenna pattern disposed on the dielectric layer. The antenna pattern includes a mesh structure in which unit cells defined by a plurality of electrode lines are assembled. A minimum distance between opposite sides facing each other in the unit cell is from 20 μm to 225 μm, and a line width of the electrode line is from 0.5 μm to 5 μm. A visual recognition of electrodes may be suppressed and a signal sensitivity may be enhanced by using the unit cell structure.
