AI Technical Summary
In MIMO-UWOC systems, existing technologies have failed to effectively optimize the transmit power allocation at the transmitter to minimize the system's average bit error rate. In particular, in turbulent ocean environments, traditional equal power allocation schemes cannot meet the requirements for communication performance.
A mathematical optimization method is used to construct a transmitter power optimization scheme with the objective of minimizing the system's average bit error rate. By considering FFIR hidden path loss and GGD ocean turbulence fading, and utilizing equal gain combining technology and the Kuhn-Tucker necessary condition, the problem is transformed into a linear programming problem to solve for the optimal power allocation at the transmitter.
Under a fixed total transmit power, the average bit error rate of the MIMO-UWOC system was significantly reduced, and the communication quality and effective transmission distance were improved.
