Experiences:
* 2002.2-2002.6: designed a viterbi and Turbo decoder for WCDMA.
* 2003.8 – 2004.5 : Cooperated with the Tsckuba university of Japan,
research on the ZCZ-CDMA systems. Implemented with FPGA and gave a report in
Japan.
* 2004.9 – 2005.6 : As one of the main designers, complemented the baseband
receiver design for GPS. Including the algorithm design, architecture
definition, software/hardware partitioning and RTL + assembly realization.
Now the chip been taped out successfully and passed the test. In this
project, I was responsible for the whole system algorithm and architecture
definition.
* 2004. 6– 2005.8, 2005.7－present：Research on the baseband algorithms for
TD-SCDMA. Now the algorithms have been completed, architecture definition
and RTL coding have been finished, vast verification is still ongoing. Up to
now, this project is all done by myself.
*　2006.11-now, beginning studying on the MAC of WiMax. Is trying to
implement the MAC protocol in NS2, including scheduling algorithms,
classifiers and ARQ etc.

The SoC lab. For multimedia and wireless communications, which is the lab. I
am with now.

whole system is all done by myself from algorithms to RTL implementation
except the DSP core.
