Neither electromagnetic nor optical technologies are suitable for communication because of their short range in this medium. Due to this, acoustic equipment is envisaged as the most appropriate technology, even though it suffers several negative effects such as strong attenuation at high (ultrasonic) ...

The underwater acoustic signal is electromagnetic (EM) and acoustic communication degraded due to multipath fading. The large systems through theoretical analysis and numerical propagation delays, low bandwidth and high bit evaluations. The results prove the feasibility of MI error rates of the under...
In this paper, in order to investigate the effect of different probability density functions (PDFs) proposed for the statistical behavior of fading under water, we evaluate the performance of underwater wireless optical communication (UWOC) systems with respect to the well-known statistical ...
The communication qualities of underwater wireless optical communication systems (UWOC) are severely limited by attenuations caused by absorption and scattering of the seawater. Hence, analyzing the underwater wireless optical channel induced by absorption and scattering is of great practical value for ...
The need for underwater wireless communications exists in applications such as remote control in off-shore oil industry, pollution monitoring in environmental systems, collection of scientific data recorded at ocean-bottom stations, speech transmission between divers and mapping of the ocean floor for ...
