“…The extracted model enables the simulation of data transmission over the characterized channel with the aim of evaluating the performance of various modulation schemes. Popular data modulation techniques used in previous works, based on acoustic guided wave propagation [4], [5], [7], [9], are the binary digital modulations such as Amplitude Shift Keying (BASK), Frequency Shift Keying (BFSK) and Phase Shift Keying (BPSK), or their variations. While binary modulations provide the lowest bandwidth efficiency, carrying just one bit per symbol, they require a lower complexity than M-ary schemes to be implemented.…”

“…They provide an alternative for data transmission in scenarios where traditional wireless or wired channels cannot be used because they are unavailable or ineffective. Prior research has investigated the use of media ranging from soil [1], [2] and a lifeline cable [3] in mining environments, to pipes meant for the transportation of water, gas or oil [4]- [7]. Applications include, but are not limited to, systems for communication in the post-accident scenario, structural health monitoring and tracking of the operating conditions of an industrial plant.…”

“…A number of publications have dealt with the in-pipe acoustic wave propagation for communication purposes. Among these, [4], [5], [9] employed waves in the ultrasonic range to induce an elastic wave in the pipe wall, while [6] provided an investigation on channel characterization for guided propagation in straight pipes. All provided practical implementations of the communication system, although the experimental demonstration was performed on a lab scaled version of a pipe in all cases.…”

The structural complexity of real-world pipeline networks makes it difficult to derive physicsbased models of acoustic propagation. This work deals with the design of a communication system based on the propagation of acoustic waves in water-filled pipes. A method based on the experimental characterization of the communication channel is proposed. This approach is applied to an urban water distribution pipeline, and a black-box model representing its frequency response is obtained. The derived two-port model is used for the simulation of a complete communication system, comprising transmitter and receiver models, with the aim of using the water pipe as a wireless communication channel. It is shown that the choice of modulation parameters is critical in order to deal with issues such as the frequency selectivity of the channel and multipath wave propagation. A communication system is presented and the experimental results of the communicated data are provided.INDEX TERMS Acoustic wave communication, channel characterization, data transmission, underwater communication, urban water supply system.

Transmission of acoustic signals between distributed sensor nodes may be useful for status monitoring of elongated structures such as pipelines. In principle, coded signals can be used in an asynchronous multiplexed system, provided the signals are distinguishable. However, multimode effects complicate signal propagation, so any such codes should be short. A search for polyphase code families with properties suitable for acoustic code division multiple access (CDMA) is presented. Algorithms for reduction of search space to allow use of a laptop for code discovery are described. Short codes of base 6 are shown to outperform codes of bases 2, 3, 4 and sets suitable for systems with 2 and 3 users are identified. The codes have similar properties to Barker codes but larger sidelobes. Their use is demonstrated by simulation and experiment at kHz frequencies using an air-filled copper pipe, an electromagnetic acoustic transducer (EMAT) and a microphone designed to excite and detect the L(0,1) mode. Low loss propagation over 25 m is achieved with a 20 kHz carrier. Excellent agreement between experiment and theory is demonstrated, with performance limited by transducer bandwidth.
