Experimental Multipath Delay Profile of Underwater Acoustic Communication Channel in Shallow Water
The shallow water channel is an environment that is of particular interest to many research fields. An underwater acoustic channel is characterized as a multipath channel. Time-varying multipath propagation is one of the major factors that limit the acoustic communication performance in shallow water. This study conducts two underwater acoustic experiments in Tanjung Balau, Johor, Malaysia. A t...
متن کاملdesign and simulation study of a short range underwater communication system employing a novel model for shallow water multipath acoustic channel in the persian gulf
in this paper, for the purpose of investigating horizontal sound propagation, based on the results obtained from practical measurements in the strait of hormoz and available data on sound speed variations at different depths, a comprehensive model for shallow water multipath underwater acoustic channel is presented. mathematical modeling of multipath effect is based on ray theory and the image ...
متن کاملProperties of underwater acoustic communication channels in shallow water.
Underwater acoustic channels are band-limited and reverberant, posing many obstacles to reliable, phase-coherent acoustic communications. While many high frequency communication experiments have been conducted in shallow water, few have carried out systematic studies on the channel properties at a time scale relevant for communications. To aid communication system design, this paper analyzes at...
متن کاملStatistical Modeling of a Shallow Water Acoustic Communication Channel
A mathematical model for the impulse response of a time-varying shallow water acoustic channel is proposed. The channel is modeled as a superposition of multiple propagation paths, whose lengths and relative delays are calculated from the channel geometry. Each path is characterized by a frequency-dependent path loss, and an additional random time-variation, expressed as a multiplicative distor...
متن کاملImplementation of an adaptive burst DQPSK receiver over shallow water acoustic channel
In an environment such as underwater channel where placing test equipments are difficult to handle, it is much practical to have hardware simulators to examine suitably designed transceivers (transmitter/receiver). The simulators of this kind will then allow researchers to observe their intentions and carry out repetitive tests to find suitable digital coding/decoding algorithms. In this p...
