Abstract:
Abstract Due to the fact that sound waves are the most effective carrier for underwater information transmission, the detection of underwater acoustic signals has become a key link in optimizing the performance of transponders in underwater positioning systems. In this paper, the signal processing module of the hydroacoustic transponder is designed to address the problem of low detection accuracy of the transponder due to the propagation deformation of hydroacoustic signals in hydroacoustic channels. The module uses the TMS320C6748 processor to achieve the transmission, acquisition, and detect

Abstract:
Abstract The article discusses hydroacoustic receiving systems, consisting of combined receivers, and the processing of the received hydroacoustic signals. Each module of the sonar system has four channels for receiving information. Spectral processing was carried out using sixteen information parameters, which made it possible to achieve the maximum noise immunity of the receiving system. Correlation processing of signals confirmed the high correlation of signals on the elements of the receiving hydroacoustic system.

Spectrum-sensing technology is crucial for the development of underwater acoustic communication networks and plays a key role in detecting spectrum holes and channel occupancy. Energy detection technology, as the fundamental spectrum sensing technology in cognitive radio, has reached a mature level of development. Its application in hydroacoustic communications can significantly enhance the utilization of the hydroacoustic spectrum. However, due to the complexity of the hydroacoustic channel compared with that of the radio channel, the traditional double-threshold energy detection technique fa

Abstract:
During data transmission in a hydroacoustic channel, one of the problems is the multipath propagation effect, which leads to a decrease in the transmission parameters and sometimes completely prevents it. Therefore, we have attempted to develop a method, which is based on a recorded hydroacoustic signal, that allows us to recreate the original (generated) signal by eliminating the multipath effect. In our method, we use cepstral analysis to eliminate replicas of the generated signal. The method has been tested in simulation and during measurements in a real environment. Additionally, the influ

Both marine mammals and hydroacoustic instruments employ underwater sound to communicate, navigate or infer information about the marine environment. Concurrent timing of acoustic activities using similar frequency regimes may result in (potentially mutual) interference of acoustic signals when both sources are within audible range of the recipient. While marine mammal fitness might be negatively impacted upon, both on individual and population level, hydroacoustic studies may generate low quality data or suffer data loss as a result of bioacoustic interference.

AbstractTerrestrial signals in marine sedimentary archives are often used for reconstructing past environments, vegetation and climate, as well as for determining sediment fluxes, pathways, and depositional sites and changes in erosional runoff. It is therefore important to understand the origin, transport, and depositional processes of the various terrestrial sedimentary components in a depositional system.

Over the past decades, signal processing methods have become increasingly widespread due to the progress of computer technology and the achievement of significant results. Signal processing is understood as the process of restoring an information message that will be accessible to human perception. To achieve this goal, there are already many mathematical methods that are applied depending on the specific problem. Working with a large data sample creates the need to create signal processing systems. An equally important factor is the limited access for human experimentation in natural conditio
