| OFDM can fully use the frequency band and transmit data with a high speed. ADSP-TS101 is a high performance DSP with good properties of parallel processing and high-speed.Aiming at the real-time processing requirement of OFDM acoustic communica- tion,an underwater acoustic communication system with rea-time processing capability was implemented.The system is composed of multiple ADSP-TS101s,multi-channel synchro- nous sampling module and FPGA for logic control.The multiple processors accomplish cluster/data flow associated multiprocessing parallel processing structure as the operation kernel and the multi-channel synchronous sample module is designed to realize no phase warp among multiple channels’data at the same time.Through experiments in a lake,it is show that the system has good stability and real-time processing capability,such that the system satisfies the technical requirement. |
