Underwater communication and its applications is a research field that has been developing rapidly, extending in many fields such as remote control in the offshore oil industry, calculating environmental pollution, transmitting voices between frogmen, drawing the ocean floor to find new resources, communication between underground devices, etc. There are two ways of establishing information exchange between underwater devices. The simplest and most effective way is using a cable connection between the transmitter and the receiver, which ensures high quality of signal and minimizes unwanted effects of the environment. However, it has disadvantages such as high cost of deploying communication, difficult maintenance, and particularly, if information exchanges take place at great depths and in mobile cases it will be very complex to ensure such exchanges. The second way is establishing information between devices using water as a signal transmission medium, which is called underwater communication channel. This article presents the basics of underwater communications including the general basis for conducting underwater communications, simulation of an underwater information system using QPSK modulation technique, and conclusion and recommendations for further research.
