Hello, there! I am the Professor of Institute of Communications Engineering at National Sun Yat-sen University (NSYSU). I received my PhD from the Institute of Communications Engineering, National Tsing Hua University, Taiwan, in 2004. I joined NSYSU after spending 5 years in industry (Industrial Technology Research Institute, Taiwan and MediaTek Inc., Taiwan). In the five years of industry, I have focused on broadband digital transceiver design.

My research style is interdisciplinary and usually combines communication technology, signal processing, data analysis, and prototyping. I am very interested in realizing the results of the research on communication prototypes and test platforms, and most of the technology have been transferred to industry. My work was selected as the best paper award by IEEE GLOBECOM 2016.

I am Editor for the IEEE Communications Letters and IEEE Wireless Communications Letters. My current research interests center around:

  • Compressed sensing
  • Smart grid
  • Secrecy
