摘　　要：为解决水下声通信的通信速率低,无线电波通信的通信距离短等问题,设计并实现了一种2ASK的水下光通信系统。该水下光通信系统使用2ASK二分键控调制方式进行调制,从而实现一定距离上的高速信号传输。在模型测试中,系统使用小功率蓝光LED进行信号传输,并在接收端处接收到发送信号,从而验证了使用2ASK进行水下光通信的可行性,并通过测试其误码率、信噪比等通信系统的关键参数,为使用BPSK,OFDM等技术的水下光通信系统提供重要参考。In order to solve the problems of low communication rate of underwater acoustic communication and short communication distance of radio wave communication, a 2ASK underwater optical communication system is designed and implemented in this paper. The 2ASK binary keying modulation mode is used in the underwater optical communication system to realize high . speed signal transmission in a certain distance. In test of the model, the feasibility of underwater optical communication with 2ASK modulation is verified by using low.power blue LED to transmit the signal and receive the sending signal at the receiving terminal. Meanwhile,the key parameters of the communication system,such as bit error rate and signal.to. noise ratio,are tested to provide an important reference for the underwater optical communication system with BPSK and OFDM technologies.
