Spectrum Monitoring and Source Separation in POWDER

Current software-defined radio systems enable transmission at nearly arbitrary frequencies, presenting the possibility of harmful interference to existing communication services when broadcasting over-the-air. The Platform for Open Wireless Data-driven Experimental Research (POWDER) provides software radios whose output can be amplified and transmitted over-the-air. POWDER must include a spectrum monitoring system that can identify users who are transmitting outside allowed frequency bands to ensure wireless spectrum license holders do not experience harmful interference.
