Assisted in development of 16ms echo canceller. Developed
various simulations/test scripts to test echo canceller
performance against ITU G.168 2000 standard.
Developed real time embedded software in C / Assembly language
on Texas Instruments TMS320C5X and TMS320C54X. Designed and
implemented signal processing algorithms for tone detection,
DTMF, Silence suppression, call processing, and echo
cancellation. Developed drivers for DSP peripheral devices.
Involved in full software development cycle from initial
requirements and design to final test and deployment.
Designed driver/boot software to program DSP software to a
flash memory device.
Debugged/integrated FSK generator for Caller I.D.
