    • One of patterns representative of instants along each TDMA frame is selected as a selected pattern in response to a unique word detection pulse produced in a current frame. With the unique word detection pulse used as a write pulse, a memory memorizes the selected pattern as a memorized pattern in a memory cell accessed by one of burst identifying flags which identify time slots in the current frame, respectively. The memorized pattern is produced as a read-out pattern when accessed by the burst identifying flag which corresponds in a next succeeding frame to the above-mentioned one burst identifying flag. A calculator produces offset representing patterns. Upon coincidence of each read-out pattern and one of the offset representing patterns, a comparator produces a receive position predicting pulse predictive of a position or a unique word detection window in the next succeeding frame. The write pulse is preferably obtained by giving the unique word detection pulse a delay which is equal to a predetermined fraction of each time slot. The offset representing patterns represent the respective instants plus an offset which is equal to a duration of each frame minus a half of a duration of each unique word detection window.
    • 响应于在当前帧中产生的唯一字检测脉冲,选择代表每个TDMA帧的时刻的一种模式作为选择的模式。 利用用作写入脉冲的唯一字检测脉冲,存储器将所选择的模式作为存储单元存储在由标识当前帧中的时隙的突发识别标志之一分别访问的存储单元中。 当由下一个后续帧中对应的突发识别标志访问上述一个突发识别标志时,存储的模式作为读出模式产生。 计算器产生偏移表示模式。 在每个读出模式和偏移表示模式中的一个一致时,比较器产生预测在下一个后续帧中的位置或唯一字检测窗口的脉冲预测的接收位置。 写入脉冲优选地通过给予唯一字检测脉冲一个等于每个时隙的预定分数的延迟来获得。 偏移表示图案表示相应的时刻加上等于每帧的持续时间减去每个唯一字检测窗口的持续时间的一半的偏移。
