In this paper, we propose the structure of bump-less high speed channel on interposer in through-via based 2.5D or 3D integrated circuit (IC). Electrical characterization of the proposed structure is analyzed by simulation in the frequency-and time-domain. In order to discuss and analyze the electrical characteristics of the proposed structure in detail, the bump-less channel and the channel with...
In this paper, a new nonlinear acoustic echo cancellation system is proposed, which utilizes adaptive 3rd-order Volterra filtering with a modified variable step-size GSPAP (VSS-GSPAP) algorithm. In particular, the proposed approach yields better echo cancellation performance than conventional VSS-NLMS methods in case of the double-talk situation in background noise. Simulation results demonstrate...
Spaceborne SAR (Synthetic Aperture Radar) image inherently contains geo-location errors which are caused by SAR image acquisition geometry, imaging mode, characteristics of reflectivity and image formation process. Since the geo-location error caused by SAR image acquisition geometry is inevitable, these errors are should be considered and corrected during the image formation process. In this paper,...
The regenerative braking system of the Hybrid Electric Vehicle (HEV) is a key technology that can improve fuel efficiency by 20∼50%, depending on motor size. In the regenerative braking system, the electronically controlled brake subsystem that directs the braking forces into four wheels independently is indispensable. This technology is currently found in the Electronic Stability Program (ESP) and...
