摘要

Currently, the modulation performances of underwater wireless optical communication are analyzed in horizontal optical transmission link. However, the methods cannot be used in vertical optical transmission link. In order to solve the problem a model of sea attenuation coefficient is proposed. The model is based on the Gaussian distribution model of chlorophyll concentration and the "seawater stratification idea". The attenuation coefficients in different depths of water can be calculated by this model. In this paper, the characteristics of bit error rate (BER) of four kinds of optical modulation modes are analyzed. The modes include OOK, PPM, FSK, and PSK. The results show that the performance of PPM is better than the others, and it is more suitable for the underwater wireless optical communication.
