Research and Development

PSI is engaged in research involving neural networks to solve signal processing problems, including automatic demodulation of Spread Spectrum signals, and threshold extension. An outgrowth of this research is the PSI developed DMP processor, which performs sequence analysis to find code generating functions. PSI provides analysis services utilizing the DMP processor.

PSI has developed a portable intercom system, using the ST001 and QFC001, which provides 3 party intercom capability at ranges up to 1500 feet.

PSI developed a QFAST™ Modem (SSM-001) to replace the Aironet 802.11 card and provide superior communications capability in high multipath environments.
