Hello! 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), where I was engaged in broadband digital transceiver design.

My research style is industrial orientation and interdisciplinary, usually combining communication, signal processing, data analytics, and prototyping. I am interested in implementing communication prototypes and testbeds.
My work was selected by the IEEE GLOBECOM 2016 as the Best Paper Award.

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

  • Deep learning for wireless physical layer
  • Compressed sensing
  • Smart grid
  • Secrecy
