Abstract
In this article, we present the proof of concept of techniques exploring ambient signals for low power and secure backscatter communications. This real-time system operates by scavenging a crowded electromagnetic spectrum and recycling active incoming signals for secure quasi-passive wireless communications. This is achieved through a low power and efficient spectrum sensing approach to identify prominent communication channels and using this energy and spectrum, to backscatter a superimposed frequency shifted signal for secure communication, utilizing a semi-passive adaptive modulation approach. No new spectral energy is added to the system in this approach, demonstrating a net zero spectral crowding or a quasi-passive opportunistic communication.
