|Revised Romanization||Jo SeongEun|
My area is in signal processing, especially matrix data. I am also interested in RTL implementation: I have experienced the RTL integration of 802.11n PHY and system design as well.
Back in academic path, I was a postdoctoral researcher with the Computer Science Department, Stanford University, Stanford, CA, working for Prof. Gene H. Golub, investigating real-time algorithms relating to total least squares (TLS). His research interests include numerical methods and optimization for systems and control, data analysis based on TLS or errors-in-variables (EIV) modeling, and applications of equality constrained minimization in adaptive algorithms such as the affine projection algorithm and the normalized LMS filtering.
