Defect recovery for iteratively-decoded data channel |
摘要 |
In iterative decoding, a data recovery scheme corrects for corrupted or defective data by incorporating results from a previous decoding iteration. In one embodiment, a final multiplexer selects between the final detector output or a previous detector output based on the absence or presence of defective data. In another embodiment, the branch metrics for the defective data, which otherwise would be combined with a priori LLRs from an outer decoder of a prior stage, are ignored so that the a priori LLRs themselves are used alone. The two embodiments can be used together. |
