| Abstract: | 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. |
