Research Assistant, Aug. 2003 - Present
Broadband Access Wireless Communications Lab, Michigan State University, East Lansing, MI 48824
Spectrally efficient anti-jamming air interface design:
Proposed a message-driven frequency hopping scheme by embedding part of the information stream
into carrier frequency selection, leading to a multiple-fold increase in spectral efficiency.
Accomplished an efficient secure communication interface design, with the OFDM framework to make
full use of the radio spectrum and an AES-based subcarrier assignment algorithm to ensure collision-free
Bandwidth efficiency increase through blind channel estimation and signal detection:
Designed a structured transmit delay scheme to enable independent information transmission at different
antennas, resulting in drastically increased efficiency compared to space-time block coding.
Developed a SOS-based blind channel estimation algorithm and signal detection approach to allow
higher data rate transmission for MIMO systems without any pilot-aid.
PHY-layer security enhancement for DS-CDMA systems:
Analyzed security weaknesses for IS-95 systems and innovated the AES-based secure scrambling,
providing significantly improved information privacy with very limited complexity burden.
Exploited the time diversity of chip-level interleaving to improve the robustness of CDMA systems in
adverse environments and enhanced built-in security through the AES-based secure block interleaving.

Adult Weight Loss project: participated in the development of a Bluetooth-based portable product used to
measure the amount of daily exercise aimed towards supporting behavior modification:
Fulfilled reading and writing functionalities using C programming for data EEPROM memory of
Designed a bandpass filter with the Direct Form II transposed structure for data stream collected by
ADXL accelerator to remove out-of-band noise.
Developed a mobile Java application using J2ME to communicate with the Bluegiga chip on the board
through UART interfaces of dsPIC30F3012 over wireless links.
WATCH project: acted as a team leader responsible for refinement of a wireless embedded system with
LCD to realize instantaneous and consistent information exchange between clients and server:
Analyzed problems, synthesized solutions, allocated tasks, documented software development process.
Achieved customized UART interfaces and functions for parsing the incoming commands to
communicate with the Bluegiga device controlled by dsPIC30F3014.
Created a real-time timer, an animation and the company logo, and displayed them on the LCD along
with the operation update.
Research Assistant, Jan. 2000 - Jun. 2003
Communication and Electronic System Lab, Univ. of Sci. & Tech. of China, Hefei, Anhui, China
Designed an instructional software of digital image processing with friendly UI using Microsoft Visual
C++ 6.0, including most of classic algorithms in image processing.
Developed an instant messenger (a text-based chat system) used in LAN through Microsoft Visual C++
6.0. Functions like user management, message forwarding and document transfer were realized.
Took charge of the project supported by Microsoft Research Asia, Image Inpainting Based On Level
Lines, as a team leader. Three inpainting algorithms based on level lines were developed to efficiently
restore damaged texture of images and later extended to image compression.
Software Engineer, Jul. 2002 - Jun. 2003

Member of the Adaptive Noise Cancellation project, responsible for checking the feasibility of the
fixed-point and float-point LMS algorithms in software, and implementing the LMS-based adaptive
algorithm into TI TMS320VC5410 DSP. The device was designed to generate synthetic sound to cancel
the environmental noise in real-time.
Built a server with friendly UI for the Network Video Surveillance System project. Three DLL filters
were constructed using Microsoft Visual C++ 6.0 to display MPEG4 real-time video with DirectShow.
