Methods for digital, phase-coherent acoustic communication date to at least the work of Stojanjovic, et al , and the added robustness afforded by improved phase tracking and compensation of Johnson, et al . This work explores the use of such methods for communications through tissue for potential biomedical applications, using the tremendous bandwidth available in commercial medical ultrasound transducers. While long-range ocean acoustic experiments have been at rates of under 100kbps, typically on the order of 1-10kbps, data rates in excess of 120Mb/s have been achieved over cm-scale distances in ultrasonic testbeds . This paper describes experimental transmission of digital communication signals through samples of real pork tissue and beef liver, achieving data rates of 20-30Mbps, demonstrating the possibility of real-time video-rate data transmission through tissue for in-body ultrasonic communications with implanted medical devices.
