Tsung-Han Yu

Tsung-Han Yu, one of the graduate students at the Cognitive Reconfigurable Embedded Systems (CORES) Laboratory at UCLA.

Tsung-Han Yu (S’10) received the B.S. and M.S. degrees in electrical engineering from National Taiwan University, Taipei, Taiwan, in 2005 and 2007, respectively. He is currently working toward the Ph.D. degree in the Department of Electrical Engineering, University of California, Los Angeles. His research is focused on digital integrated circuits and architectures for communication signal processing. Now he is working on development of algorithm and circuit architecture on wideband spectrum sensing for cognitive radios.
