OPTIMUM FRAME SYNCHRONIZATION AND PERFORMANCE IN A BINARY SYMMETRIC CHANNEL
-
摘要: 本文論證了固定幀長度相關法是二進對稱信道(BSC)的最佳幀同步算法。并用Poisson分布和Markov鏈導出了一次通過幀同步捕獲概率,鎖定概率以及進入鎖定的平均時間,還給出了計算機模擬結果。與傳統(tǒng)的門限法比較,本文給出的算法性能好,實現容易,有很大的應用價值。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.
