水声信道高速率数据传输技术
High-rate data transmission techniques in underwater acoustic channels
Abstract
本文介绍近年来水声信道高速率数据传输技术的一些研究进展，并结合本所研究的水声数据遥测，数字语音通讯和视频图象传输实验样机，讨论了具有抗多途干扰的声传输系统在调制信号设计及信号处理上所采用的关键技术。 Recent certain advances in high-rate data transmission techniques in underwater acoustic channels are introduced.By presenting the prototypes of underwater telemetry and telecontrol, underwater digital acoustic communications, underwater visual image transmission which we have studied and implemented, the key techniques of an anti-mutipath acoustic transmission system in the choice of signal design and signal processing are discussed.
