This document proposes that a network routing protocol, such as the popular Internet Protocol (IP), can be combined with high speed switching fabrics to create a hardware independent routing environment for software radio. The flexible routing provided by such a network layer would allow signal… More

The proposed approach leverages a proven RF stimulation technique to detect transceivers within a 5m range for physical security applications. The proposed tasks will evaluate operational scenarios for transceiver detection, and will determine the effectiveness of the detection and classification… More

This Small Business Technology Transfer (STTR) Phase I research project aims to prove the feasibility of Direct Phase Antenna Modulation (DPAM), an innovative wireless communication signaling technology that promises to greatly enhance spectral efficiency and multi-user interference, while reducing… More

As miniature, radiofrequency (RF) transceivers grow in widespread use and capability, their deliberate or inadvertent infiltration into secure areas poses a growing threat to national security. Manual searches and metal detectors at checkpoints are at best inefficient and generally ineffective at… More

We propose an analog transmission of a speech cepstrum for the dual purposes of bandwidth reduction and improvements in speech quality under extremely challenging channel environments. By utilizing the speech cepstrum, we exploit a well-studied and widely-used sparse representation of speech. The… More

Project Pika addresses the challenge of receiving messages on a radio channel when multiple users inadvertently collide on the channelan event that is especially likely during times of disaster or emergency. In Phase I we demonstrated the feasibility of this signal source separation through analysis… More

The Global Information Grid (GIG) has access to massive amounts of data from a vast number of sensors and sources. Extracting information from this quantity of sensor data is a significant challenge. Sensor data is often large, which taxes limited-bandwidth GIG interconnections. Current approaches… More
