摘　　要：为实现水下平台间稳定高速的信息传输,论文搭建了一个基于并行组合映射序列扩频的水下通信系统,从稳定性、隐蔽性、经济性、工程实现性对该系统进行了深入分析。最后通过消声水池实验验证了该系统在低信噪比条件下仍能保持信息的稳定输送,较直接扩频通信而言,在保持通信稳定的基础上大幅度提高了通信速率。In order to achieve stable and high-speed information transmission between underwater platforms,an underwater communication system based on parallel combinatorial mapping sequence spread spectrum is built in this paper. Finally,the experi? ment in the anechoic tank proves that the system can still maintain the stable transmission of information under the condition of low signal-to-noise ratio. Compared with direct spread spectrum communication,the communication rate is greatly increased on the basis of maintaining the stability of communication.
