Abstract

In this paper, we look into a Jong Nang Channel which is the origin of digital communications and has been used in Jeju Island since AD 1234. It is one kind of communication ways which informs people of whether a house owner is in one's house or not using its own protocol. It is comprised of three timber and two stone pillars whose one side has three holes respectively. In this paper, we analyze the Jong-Nang Channel both in the light of logic and bit error probability. In addition, we compare it with a conventional binary erasure channel when some errors occur over them respectively. We also show that a capacity of NOR channel approaches Shannon limit.

디지털 통신의 기원인 정낭(입구대문(入口大門))이 1234년부터 제주도에서 사용되어왔다. 정낭은 집의 입구에 서까래 크기 나무 3개를 돌기둥에 삽입해 집안에 사람이 있는지 유무를 알리는 통신 방식이다. 본 논문에서는 정낭의 논리적 분석을 하고 정낭 채널에 오류를 분석한다. 정낭이 잘못 놓았을 때 오류를 분석하는데 통신 시스템이 이진 대칭 채널과 비교하고, NOR 채널에서 채널 용량이 샤논 이론에 접근하는 것을 보인다.
