Chaotic behavior in systems, Signal processing--Mathematics, Joint sonar-communication (SonComm) system


An ever increasing number of actively interconnected wireless devices tend to exert congestion on the naturally limited resources provided by the electromagnetic spectrum. This fact imposes a significant engineering challenge on efficient utilization of communication channels. One method to lessen the stringency of the spectrum access is to combine functionality of wireless applications via jointly operational (multi-purpose) waveforms. Solvable chaos was previously shown to have inherent detection benefits when used independently in practical demonstrations of either acoustic ranging or communication. This dissertation focuses on the design of a joint sonar-communication (SonComm) system via solvable chaotic waveforms. First, individual hardware demonstrations that enable the advancement of a joint implementation are presented. These individual demonstrations include i) a study on using solvable chaos as a tool to evaluate a matched filter receiver performance, ii) experimental synchronization of solvable chaos which promotes its potential use in communication, clock recovery, etc., and iii) demonstration of a successful acoustic ranging system using a reduced hardware sonar. The latter part of this dissertation focuses on the implementation of a joint SonComm system. Since solvable chaotic waveforms can act as a source of binary information, their use for SonComm application is highlighted. Finally, the design and experimental validation of the joint SonComm system is presented as a demonstration of the dual purpose of ranging and communication using a single source of solvable chaotic waveforms.
