Examples of DSP algorithm, software, and hardware projects.
Projects have been performed for various clients include
- Developed algorithms and hardware/software solution to
correct the freuency response of a low-cost throat microphone.
After correction the sound quality is comparable to a
conventional microphone, but the noise
rejection is much better.
- Data acquisition and digital filtering implemented in
assembly/C for an Analog Devices TigerSharc processor.
- Software for speech noise reduction and bandwidth expansion.
- Demodulation of PSK, OFDM, and other modulation waveforms.
Self-funded projects (for which I can provide details) include:
-
Some work on speech recognition in noise.
robospeechrec. I'm
using the Sphinx open source recognizer and plan
to post many of my components as open source also.
-
I recently completed an IEEE-sponsored course in advanced techniques for
FPGA development. Some things being
done for that course are described here.
-
Implementaton of a Reed-Solomon encoder and decoder for the Analog Devices
Blackfin processor. This software is now available under the GNU General
Public License (GPL). Click here for more details.
-
Implementation of an audio processing system using the Texas Instruments
MSP430 processor. This unit runs on a single AA battery, is intended
to perform data capture and digital filtering on an audio data stream.
-
A voltage booster, to convert the output of a single NiMH or NiCd battery
to 3.3 volts. Intended for the MSP430,
but applicable to any 3.3 volt low power processor.
-
A voice synthesizer implemented in the Cypress
Programmable System-on-a-Chip (PSoC). More info:

-
An in-house project to implement data acquisition using
an Anadigm Field Programmable Analog Array chip.
