-
摘要: 本文論證了固定幀長(zhǎng)度相關(guān)法是二進(jìn)對(duì)稱信道(BSC)的最佳幀同步算法。并用Poisson分布和Markov鏈導(dǎo)出了一次通過(guò)幀同步捕獲概率,鎖定概率以及進(jìn)入鎖定的平均時(shí)間,還給出了計(jì)算機(jī)模擬結(jié)果。與傳統(tǒng)的門(mén)限法比較,本文給出的算法性能好,實(shí)現(xiàn)容易,有很大的應(yīng)用價(jià)值。

Abstract: The fixed frame length maximum correlation method which is the optimum method in a binary symmetric channel has been proved. With Poisson distribution, the frame sync acquisition probability is obtained and followed by computer simulation. By Markov modeling techniques, the probability and the mean time into lock mode are given. Finally, it is shown that the optimum frame sync method is far superior to conventional, and it is very useful in practice. -
