摘　　要：从现行的水下通信技术入手,运用蓝绿激光脉冲作为通信信号的载体,针对复杂的水下信道对通信信号产生的吸收、散射以及噪声干扰,研究了一种基于水下通信的分集接收技术──时频调制技术。This paper proceeds with current communication under water. By using blue-green laser as a communication signal carrier, and in view of absorption, scattering and noise inference produced by the under-water channel when the communication signals travel in the channel, a kind of diversity reception technique based on communication under water is developed, known as Time-frequency shift keying（TFSK）.

关 键 词：水下通信 分集接收技术 时频调制
