摘      要：Inductive coupling transmission system is an important measurement device for acquiring and transmitting marine environmental ***,low transmission rate cannot meet the current demand for large data transmission in marine environment detection at *** order to improve the transmission performance of the system in practical communication system,optimizing the design by directly changing the circuit parameters is time-consuming and ***,a set of inductive coupling transmission channel analysis system is designed based on virtual instrument to improve the transmission rate and reliability of inductive coupling transmission *** bit error rate of channel system at different frequency and noise levels are tested by using three kinds of digital modulation mode including amplitude shift keying(ASK),frequency shift keying(FSK)and differential phase shift keying(DPSK),taking square wave and sine wave as a ***,the sine wave is selected to be carrier signal and DPSK is chosen to be modulation *** reliable transmission of signal with the error rate less than0.005and the transmission rate of9600bps,at the noise level of-10dB,is realized and verified by the debugging circuit experiments with multi-nodes in the *** study provides an important experimental evidence for improving signal transmission reliability of inductive coupling transmission system.
