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