摘要
Abstract
There are serious Doppler frequency shift and a lot of impulse noises in the underwater acoustic channels which increases difficulties for realizing communication synchronization. The synchronization windage will cause the best sampling position offset which will also deteriorate the effects of communication algorithm afterwards. In order to realize accurate communication synchronization in the abominable underwater acoustic environments, this article brings forward a new algorithm for phase modulated systems consisting of frame synchronization and bit synchronization based on the respective advantages of linear frequency modulated series and m series. Using the algorithm is checked to be valid by simulations as well as experiments carried out in lake and river.关键词
