摘要: Survivor sequences information is supplied to a RAM 61-1 and a RAM 61-2 as an input Din. The RAM 61-1 and the RAM 61-2 perform an interleaving operation and store the survivor sequences information alternately in accordance with a clock CK1 and a clock CK2 differing in phase from the clock CK1 by half a period. The phases of the clock CK1 and the phase of the clock CK2 are delayed by half a period when a write operation is switched to a read operation with data being outputted at a selector 62 in an appropriate order accordingly. Traced-back data is then inputted from terminal A and terminal B to the selector 62 and outputted from a terminal X after one of these items of data has been selected at a prescribed timing.

摘要翻译: 幸存者序列信息被提供给作为输入Din的RAM 61-1和RAM 61-2。 RAM 61-1和RAM 61-2执行交织操作,并根据与时钟CK1相位不同半个周期的时钟CK1和时钟CK2交替地存储幸存器序列信息。 时钟CK1的相位和时钟CK2的相位在将写入操作切换到读取操作时延迟半个周期,其中数据在选择器62处以相应的顺序输出。 然后,在规定的时刻选择了这些数据项中的一个之后,从终端A和终端B向选择器62输入追踪数据并从终端X输出。
