Link-16에서 시간 동기를 위한 충돌 확률 성능 분석

초록

In this paper, we analyze the collision probability among JU(Joint Tactical Information Distribution System Unit)s that occur in the fine synchronization of Link-16, a tactical data link standard, and calculate the probability that JUs attempt fine synchronization in each time slot and the total number of JUs needed for reliable communication. We derive the probability that each JU will succeed in fine synchronization, the probability of success at least once when fine synchronization is attempted consecutively, the probability of all JUs to succeed at least once for some fine synchronization attempts, and the parameter condition needed for the probability of all JUs to succeed at a value of or more where denotes the significance level. We propose a method for optimizing the reliability and efficiency of the Link-16’s fine synchronization system by verifying the validity of a derived probability formula through computer simulation experiments.
