Scottsdale, AZ - 20 July 2018 - Bedford Signals Corporation demonstrated Scalable Collaborative Cancellation Radios (SCCRs) on 16 through 18 July 2018 at Fort A.P. Hill Virginia for U.S. Special Operations Command (USSOCOM) Technical Experimentation Event 18.3 for Command, Control, Communications and Computers (C4), Intelligence Surveillance Reconnaissance (ISR), Small Unmanned Aerial Systems (SUAS), and Mobility. These single antenna radios use wireless cooperation to mitigate interference from frequency re-use, a nearby high power transmitter, or intentional jammers. The SCCRs were developed under a Small Business Innovation Research (SBIR) Phase II solicitation by DARPA. Wireless communication between remote single antenna soldier radios can be limited by jamming, fading, and loss over distance. Transmit and receive collaboration among local radios provides signal gain for a longer communications range, along with cancellation of any jammer type. SCCR techniques will provide a small group of 4 soldiers with twice the range or at least 30 dB mitigation of a challenging white noise jammer. Successful implementation required two key innovations. Our first is an efficiently scalable hierarchical protocol that reduces overhead, distributes computation, and improves performance. Our second is the advanced signal processing necessary to provide deep interference cancellation using collaborative radios having different delays and doppler shifts. Our collaboration is compatible with multiple antenna radios and synergistic with external cancellers. Bedford Signals Corporation is a privately held company, established in May of 2003 to hurdle the challenges of high bandwidth Digital Signal Processing for Satellite and Terrestrial Communications Systems. Core competencies include communications systems, networks, and protocols - with a focus on sophisticated spatial and temporal array processing for wireless communications systems. Contact: |
