摘　　要：传统的自适应跳频通信可以克服水声多径信道时变、频变、空变给通信质量带来的影响,在频率选择性衰落的信道上保证高质量的数据传输。基于概率的自适应跳频通信在传统的自适应跳频通信的基础上,根据信道通信质量的好坏分配不同的使用概率,能够进一步提高系统的可靠性和安全性。在水声通信中,多普勒现象非常明显。在水声基于概率的自适应跳频通信系统中,引入多普勒频移补偿能够进一步提高通信系统的可靠性。Traditional adaptive frequency hopping communication can overcome the influence of underwater acoustic multipath channel time variation,frequency variation and space variation on communication quality,and ensure high-quality data transmission on frequency selective fading channels.Based on the traditional adaptive frequency hopping communication,the probabilities-based adaptive frequency hopping communication can further improve the reliability and security of the system by allocating different use probabilities according to channel communication qualities.In underwater acoustic communication,Doppler phenomenon is very obvious.The introduction of Doppler frequency shift compensation in the probabilities-based adaptive frequency hopping communication system can further improve the reliability of the communication system.
