Abstract: A received frame is provided to a first decoder and a first time reverse unit. The first decoder decodes the provided frame and outputs the decoded frame. The first time reverse unit reverses bits of the provided frame in time direction and outputs the time reversed frame. The time reversed frame is provided to a second decoder. The second decoder decodes the time reversed frame. This decoded frame is then provided to a second time reverse unit. The second time reverse unit reverses bits of the decoded frame in time direction and outputs the frame. The frame is outputted from the first decoder is compared with the frame is outputted from the second time reverse unit by comparator. If any difference exist between the two frames then the received frame is judged as unreliable.

Abstract translation: 接收的帧被提供给第一解码器和第一时间反向单元。 第一解码器解码提供的帧并输出解码的帧。 第一次反转单元在时间方向反转所提供的帧的位，并输出时间反转帧。 将时间反转帧提供给第二解码器。 第二个解码器解码时间反转帧。 然后将该解码帧提供给第二时间反向单元。 第二次反转单元在时间方向上反转解码帧的位并输出帧。 将从第一解码器输出的帧与比较器从第二时间反向单元输出帧进行比较。 如果两帧之间存在任何差异，则接收的帧被判定为不可靠。
