DETAILS OF 2 RECENT PROJECTS:

SOFTWARE: Designed small database in VBA for

Excel. Allows data entry by inexperienced users, through custom forms. Wrote

associated HELP file and explanation of how the program works. Am currently

responsible for maintenance of this program.

HARDWARE: Design and Test of 9600 bps low-power

(1 mA at 3 volt) 8PSK modem for use in industrial process control. The modem is

eventually to be integrated into a single IC. It uses many available modern techniques

such as matched filtering, raised cosine filtering, equalization, Costas Loop. This

involved simulation using PSPICE and MATLAB, understanding and use of DSP with integer

math, C code for generating look-up tables, overseeing FPGA and VHDL work, and determining

overall chip architecture.
