| description | In order to mitigate the crosstalk caused by oceanic turbulence in the underwater wireless orbital angular momentum multiplexing optical communication system, the application of space-time coding technology in the system was studied.Based on Rytov approximation, the covariance method and interpolation method were used to simulate correlated random phase screens and then the influence of time-varying oceanic turbulence channel on orbital angular momentum signal was studied.The transmission characteristics of orbital angular momentum multiplexing optical communication system with space-time coding was analyzed by simulation.The phase structure function of the time-varying phase screens and the detection probability distribution of the beam carrying the orbital angular momentum through the time-varying simulation channel were in line with theoretical expectations.The simulation results show that the space-time coding technology can effectively mitigate the influence of ocean turbulence on the system bit error rate. |
