Abstract
Through analyzing the transmission characteristics of Ultrasonic on Ultrasonic transducer, this paper gets channel parameters of ultrasonic transmission. And a new model of ultrasonic channel is given in Matlab/Simulation environment. Using this model, FSK-DSSS communication system is realized according to theoretical analysis and experimental test. Finally this paper shows relationship between the SNR and Bit Error Rate, which proves that this system has good noise immunity. Data can be demodulated successfully when the SNR is above -10 dB
