A Study on Technique to Process the Distress Signal of Digital Selective Calling

This study is on the technique to process the distress signal of the DSC message. In this study, we analyzed recommendations which prescribed the frequencies, operational procedures and technical sequence of the DSC, RR, amendments to the 1974 SOLAS convention also domestic Radio Regulation fur the development, suggested the basic circuit to be materialize the function of a distress alert on the DSC equipment using Microprocessor(uPD70325), constructed the algorithm of processing a message, programmed and compiled it in C language. With adopted the additional functions and connected with peripheral circuits, it could be applied to development of real equipment.
