초록
In this paper, we propose a system that can be used to provide the national standard time for the general public with ease by using the self-implemented independent time-code generator for transmitting standard time information through both the wired and the wireless networks. The newly proposed time code is different from conventional methods in the point that it has a structural advantage of having an ability of obtaining reliable data by repeatedly transmitting the same information. We observe that it is sufficiently possible to transmit the time information with a microsecond level because measurement result shows that the system uncertainty is about few nanosecond of time-error fluctuation through the self characteristic measurement of total system including the time-code generator and decoder system receiving time-information.
