Ultrasonic Backscatter Communication: A Feasibility Study

This paper presents a feasibility study of an ultrasonic backscatter communication system designed for low-power, short-range data transmission, suitable for applications in IoT, biomedical implants, and underwater sensor networks. Our proposed system utilizes a very low power passive network to encode information by modulating the reflection properties of the backscatter medium. We demonstrate through experimental analysis the effective data transmission and detection. The key contribution of this study includes the development of a practical experimental setup using ultrasonic transducers, backscatter modulators, alongside signal processing techniques for optimal data extraction. Results indicate the successful data transmission and detection for a limited number of bits in a very high SNR regime, showcasing the performance of the transmission protocol.
