Digital data decoder with improved unreliable frame detection performance |
摘要 |
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.
