Researches And Designs On Maritime Automatic Radio Telex System

Under the development of communication technology. MORSE has not fit in with the needs of modern communication. In accordance with the condition of short wave communication , This dissertation focuses on analysis and researches designs of maritime automatic radio telex system after morse will be replaced. It contains these content:Introduction the fundamentals of designing automatic radio telex system , especially ARQ( Automatic Request for Repetition) and FEC (Forward Error Correction.The network of the ART system is studied, consist of network technique and network frame, especially realization of network functioaDesign and discuss the hardware equipment MODEM of ART System, consist of design scheme, fundamental technique and detection technique.ART system change the operating key by hand to operating keyboard, the communication between vessel and land subscriber accomplish by computer and need not intervene by coast operator, realizing the auto communication. The transmission way increase the E-MAIL,FAX, TELEX. The communication of maritime short wave will take place the leap by this system.
