Reduction of the Multipath Propagation Effect in a Hydroacoustic Channel Using Filtration in Cepstrum [PDF]
Sensors, 2020 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,

A Belief Propagation Algorithm for Multipath-Based SLAM
IEEE Transactions on Wireless Communications, 2019 We present a simultaneous localization and mapping (SLAM) algorithm that is based on radio signals and the association of specular multipath components (MPCs) with geometric features. Especially in indoor scenarios, robust localization from radio signals is challenging due to diffuse multipath propagation, unknown MPC-feature association, and limited ...

Extreme Rhythm Keeping in Long‐Range Slow Click Communication of Sperm Whales [PDF]
Annals of the New York Academy of Sciences, Volume 1559, Issue 1, May 2026.In this study, we show that male sperm whales produce low‐frequency slow clicks at low repetition rates with extreme source levels > 200 dB re 1 µPa (pp), making them the loudest mammalian communication signal, with an estimated active space of ∼70 km.

Off-Grid DOA Estimation Based on Compressed Sensing on Multipath Environment
International Journal of Antennas and Propagation, 2023 Due to the existence of multipath propagation, the array will receive the multipath propagation signals at the same time while receiving the target signal and the performance of directional of arrival (DOA) estimation will be influenced.

Development and Validation of a Multipath Mitigation Technique Using Multi-Correlator Structures
Navigation, 2023 Multipath propagation is a major source of error in global navigation satellite systems (GNSSs), especially in urban environments. This is because conventional GNSS receivers can provide biased range estimates that lead to positioning errors.
