| 摘 要： | 本文论证了固定帧长度相关法是二进对称信道(BSC)的最佳帧同步算法。并用Poisson分布和Markov链导出了一次通过帧同步捕获概率,锁定概率以及进入锁定的平均时间,还给出了计算机模拟结果。与传统的门限法比较,本文给出的算法性能好,实现容易,有很大的应用价值。

| 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. |
