A novel high frequency digital transceiver scheme using audio port as signal modulation and demodulation interface is proposed. The system adding human-computer interaction module, business service module, base station modulation and demodulation module, shipboard modulation and demodulation module, and using advanced modern digital signal processing algorithm to complete signal modulation and demodulation in digital domain, which overcomes the anti-interference ability of analog demodulation circuit poor power, low spectrum utilization, poor user experience and other shortcomings. The simulation results show that when SNR of the baseband is 4.9dB, the BER of the system can reach about 10 −4 , the design scheme can meet the ITU-R M.2058-0 recommendation and the actual communication requirements.
