PROFESSIONAL EXPERIENCE

LoJack Corporation, Engineering Department

Senior DSP Engineer

(February 2008 - present)

. Firmware lead to develop Home Monitoring Unit (HMU) for Person-At-Risk

(PAR) project. The core processor was ARM and also used commercial RTOS,

IAR PowerPac.

o Worked with management team, hardware and RF groups to generate

engineering specifications and reports for new product. Conducted

design reviews to ensure all objectives are fulfilled.

o Scope of responsibility also included architectural design,

implementation of critical functional modules, system integration,

test and evaluation of hardware and firmware for microprocessor boards

of wireless electrical equipment.

o Provided technical leadership during design and debug phase to meet

deployment timelines.

. Core engineer member to develop Network Repeat Unit. This product

utilized ADSP-

Blackfin 537 and CLinux as RTOS.

o Designed and developed wireless receiver module from concept to

production release.

o Debugged, tested and troubleshoot embedded DSP algorithm firmware.

o Provided improvement and modification of the design that maximized

performance.

. Core engineer member among the multifunctional design team of Vehicle

Locating Unit (VLU) to develop low power consumption solution for large

volume production of embedded electrical devices. MSP 430 is the

microcontroller and compiler is IAR.

o Performed conceptual and detailed design and implementation of

critical RF elements, including transmitter (modulation), receiver

(demodulation) and synchronization to LoJack RF towers.

o Worked closely with customers and marketing engineers to define and

specify integrated solutions for RF wireless products.

Firmware Engineer (October

2007 - February 2008)

Participated in developing the projects of Listening Post (LP) and Tower

Simulator.

. Prototyped, programmed and debugged firmware including peripheral device

drivers, timing and program logic on MSP 430 Microcontroller.

. Developed programs to support design verification, qualification, and

board level functional testing.

The University of Toledo, Electrical Engineering and Computer Science

Department

Research Assistant

(August 2001 - August 2007)

Conducted research projects in the fields of digital wireless

communications, audio and image processing, computer networks etc.

. Designed various DSP algorithms and communication techniques to simulate,

implement and analyze the functional blocks of On-Board Processing (OBP)

regenerative receiver for MF-TDMA signal in the presence of various

degrading factors. The simulation was conducted in Matlab. The project

was sponsored by ETRI (Electronics and Telecommunications Research

Institute).

. Designed and implemented partial processing receiver for the frequency

hopping FDMA in jamming environment. Software development was implemented

in Borland C. The project was sponsored by Samsung Thales Co, LTD.

. Implemented the first four layers of the OSI model for computer networks,

i.e. transport layer, network layer, datalink layer and physical layer,

using C++ in Solaris UNIX.

. Implemented a 32-bit divider, using division through multiplication

algorithm, and evaluating the performance of its behavioral and

structural architecture in VHDL code.

. Implemented JPEG compression, Vector Quantization compression, digital

watermarking in Wavelet domain etc. in image processing area.

. Implemented AMDF algorithm for pitch identification of human voice using

Matlab.
