摘　　要：介绍了一种应用于浅海的基于定点DSP的跳频水声遥控通讯及控制技术.在浅海环境水声信道的多途效应造成水声通讯质量急剧下降的情况下,利用跳频编码抗多途干扰的优势及DSP芯片强大的实时数据处理功能,实现低误码率的水声遥控和控制.目前该技术已成功地应用于相关试验控制系统中.The underwater acoustic communication (UAC) and control with fixed-point DSP technique is introduced. Confronting the multi-path effect of the underwater acoustic channel which leads to the deep reduction of communication quality, the JF (jump frequency) coding and the powerful real-time data processing function of DSP are used to reduce the high error code rate. This technique is now used in the relevant experimental control system successfully.
