ONE-PASS ACQUISITION PROBABILITY FOR FRAME SYNCHRONIZATION
-
摘要: 本文讨论了二进数据帧同步理论问题,引进了随机数据对帧同步捕获的影响。在同步图像长度和结构、帧长度、误码率、判决门限之间建立了数学表达式,即一次通过捕获概率表达式。最后还给出了最佳帧结构设计方法。并对信道效率与捕获概率之间的关系作了简单说明。

Abstract: The theory of binary digital frame synchronization is discussed. The effect of random data on frame synchronization is introduced. The one-pass acquisition probability expression which is related with the pattern length and construction, frame length, bit error rate, decision threshold is obtained. Finally the method of design about optimal frame format is given and the relation between efficiency of channel and acquisition probability is described. -
