    Abstract: In a Forward Error Correction (FEC) technique, parity vectors are computed such that: each parity vector spans a set of frames; a subset of bits of each frame is associated with parity bits in each parity vector; and a location of parity bits associated with one frame in one parity vector is different from that of parity bits associated with the frame in another parity vector. Values of decoded hits of a first frame are deduced from known parity bits of a first parity vector having an effective length of one frame. For parity vectors having, an effective length greater than one frame, a Log Likelihood Ratio of each unknown parity bit associated with the first frame is updated based on known and unknown parity bits of each parity valor. The first frame is decoded using the deduced bit values and the updated LLR values.

    Abstract translation: 在前向纠错（FEC）技术中，计算奇偶校验向量，使得：每个奇偶校验向量跨越一组帧; 每个帧的比特的子集与每个奇偶校验向量中的奇偶校验位相关联; 并且与一个奇偶校验向量中的一帧相关联的奇偶校验位的位置与在另一个奇偶校验向量中与该帧相关联的奇偶校验位的位置不同。 从具有一帧的有效长度的第一奇偶校验向量的已知奇偶校验位推导第一帧的解码命中的值。 对于具有大于一帧的有效长度的奇偶校验向量，基于每个奇偶校验的已知和未知奇偶校验位来更新与第一帧相关联的每个未知奇偶校验位的对数似然比。 使用推导的比特值和更新的LLR值对第一帧进行解码。

    Abstract: A system and method for using a cyclic redundancy check (CRC) to evaluate error corrections. A set of data and initial CRC values associated therewith may be received. The set of data by changing a sub-set of the data may be corrected. Intermediate CRC values may be computed for the entire uncorrected set of data in parallel with said correcting. Supplemental CRC values may be computed for only the sub-set of changed data after said correcting. The intermediate and supplemental CRC values may be combined to generate CRC values for the entire corrected set of data. The validity of the corrected set of data may be evaluated by comparing the combined CRC values with the initial CRC values.
