| 摘 要： | 本文提出了一种利用帧同步码（以下简称帧码）符合度特征，采用多比特观测窗口技术的数字相关检测模型，基于上述模型，采用神经网络实现了这种数字相关检测器。实验结果表明：该数字相关检测器对帧码出现的误码和码元滑动的情况均有较高的检测率。

| Abstract: | A digital correlation detector model,which takes advantage of the frame synchronization pattern feature of degree of coincidence and adopts a multiple bit detection window,is proposed in this paper Based on this model,a new digital correlation detector with a neural network is designed The experimental result shows that this detector has high detection rate and can recognize frame synchronization pattern with error bits and slippage bits correctly |
