在大多数应用中，水声传输必须适应环境条件（垂直、水平或倾斜链路、多径、噪声等）。多调制声传输系统是一种新型的调制解调器设备，它的调制方案和波特率由操作者远程控制。在同一系统中实现三种类型的调制：用于垂直传输的相移键控（PSK），用于水平通信的啁啾和跳频调制。用户可以实时选择两个主要参数（调制和波特率），测试传输的可靠性，最终决定采用哪种调制方案和波特率可以保证最佳的质量。水下装置然后通过声学链路远程编程。详细介绍了该系统，重点介绍了在海上作战中获得的调制类型
In most applications, underwater acoustic transmissions have to be adapted to the environmental conditions (vertical, horizontal or slant link, multipaths, noise...). The multimodulation acoustic transmission system is a newly designed equipment which acts as a modem whose modulation schemes and baud rates are remotely controlled by the operator. Three types of modulation are implemented in the same system: phase shift keying (PSK) for vertical transmission, chirp and frequency hopping modulations for horizontal communication. The user can select in real time the two main parameters (modulation and baud rate), test the reliability of the transmission and finally decide to use the modulation scheme and the baud rate which will insure the best quality. The underwater unit is then remotely programmed by the acoustic link. The system is described in detail with emphasis on the types of modulation results obtained during campaigns at sea are presented.<<ETX>>
