Abstract:
Using the underwater acoustic channel (UWA) for information dissemination requires a high data rate. However, some phenomena like refraction, reflection, phase shift, and high attenuation are undesirably apparent when the subject of using UWA is raised. Accordingly, sound communication would be a highly challenging task to be accomplished. Therefore, proposing a model of acoustic underwater communication channels is critical because of the multipath interference originating from the surface and bottom of the ocean. In this contribution, a straightforward geometry channel model for vertical and horizontal marine communications is presented. To do so, transmission loss and channel impulse response are analyzed as a function of transmitter and receiver distance, water depth, and reflection rate. The results of the model proposed in this paper are in very good agreement with those available in the literature. Initial findings indicate that the delay spread of horizontal communication with a 1 000 m range reaches79 ms and 0.3 s for 30 m vertical communication.
