Abstract

Aiming at the problem of optical intensity fluctuation under strong turbulence in underwater visible light communication, a beamforming algorithm based on maximum ratio combining is proposed. Through space diversity, the received signals are combined through different paths, and a beamforming optimization model with the goal of maximizing the signal-to-noise ratio is established to solve the optimal beamforming vector to form the target beam and overcome the influence of strong turbulence channel fading. The simulation results show that at a bit error rate of 10⁻⁶ , compared with a system without use the beamforming algorithm, the signal-to-noise ratio of the system is reduced by about 5dB.
