Abstract—In this paper, a design of ultraphonic tubulous water communication system based on OFDM is introduced. The system takes PL3106 which is embedded enhanced 8051 microprocessor as the control chip and takes TMS320VC5509 as the core of OFDM modulation-demodulation. In the paper, the principle of OFDM is introduced briefly. The hardware and software of the system are designed and the experimental results are analysed and concluded.
Keywords—Ultraphonic tubulous water communication; Orthogonal Frequency Division Multiplexing (OFDM); channel attenuation; multipath effect; ultrasonic transducer
