Algorithm of Water-Air Trans-Medium Communication Based on Acousto-Optic System

Abstract

To achieve underwater-aerial trans-medium uplink wireless communication, based on the laser interference detection of underwater acoustic signals, attenuation curves of acoustic signals at various water depths to the water surface and micro-vibration curves on the water surface caused by different underwater acoustic power frequency signals were obtained through simulation calculations. A quantitative relationship between underwater sound source characteristics and disturbances on the water surface was established. Code elements for trans-medium communication were designed, and various demodulation methods were compared. The impact of parameter variations on the transmission error rate was analyzed, and modulation and demodulation simulations of acoustic-laser communication were achieved.
