In this thesis, we present alternative ways to overcome nonideal behaviors of acoustic communication media and devices to achieve higher performance than possible through standard communication techniques for ideal linear channels. In the first part of this thesis, we focus on ultrasonic communication through soft tissues for biomedical applications. We first present an ultrasonic through-body communication system capable of video streaming through biological tissues and animal subjects. We then examine the effects of acoustic nonlinearity on communication signals and develop a receiver that can compensate for the distortion introduced by the nonlinear through-tissue channel. In the second part of this thesis, we focus on through-air acoustic communication between personal computers using near-ultrasonic audio frequencies. We first develop a software-defined near-ultrasonic modem that uses the built-in laptop microphones and speakers to transmit short messages quickly, locally, and inaudibly. We then focus on the effect of audio system nonlinearities on the communication performance and present a neural-network-based receiver for a nonlinear near-ultrasonic communication system."]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["High data rate acoustic communications with nonideal channels"]}]}],"canonical_facts":{"dc:contributor":["Singer, Andrew C","Hanumolu, Pavan Kumar","Oelze, Michael L","Smaragdis, Paris"],"dc:creator":["Tabak, Gizem"],"dc:date":["2022-12","2022-12-02"],"dc:description":["Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-12-01","The student, Gizem Tabak, accepted the attached license on 2022-12-01 at 12:09.","The student, Gizem Tabak, submitted this Dissertation for approval on 2022-12-01 at 12:27.","This Dissertation was approved for publication on 2022-12-02 at 07:19.","DSpace SAF Submission Ingestion Package generated from Vireo submission #18661 on 2023-04-12 at 11:35:21","Radio-frequency (RF) electromagnetic waves provide valuable connectivity in wireless communication applications such as radio, television, and wireless internet.
