摘要： A method and apparatus for decoding a linear block encoded string of information bits comprising: converting the string into a plurality of codewords. Performing hard and soft decision on each codeword to generate a hard and soft decision vector. Computing the syndrome and finding the location of the two minimum values by Galois Field Arithmetic. Designating these values LOW1 and LOW2 and xoring with a Nc1, thus generating Nc2. Swapping Nc1 with Nc2 and determining the lowest soft decision value, Min1 and a next lowest value, Min2. The two bit locations creating Min1 are designated as MinA and MinB. MinA being replaced with Min2 minus the value MinA. MinB being replaced with Min2 minus the value at MinB. Generating an output codeword by subtracting Min1 from all other bit locations values and 2's complementing all soft values with 0 in their location. Creating the new soft value vector.
摘要翻译：一种用于对线性块编码的信息比特串进行解码的方法和装置，包括：将该字符串转换成多个码字。对每个码字执行硬和软判决，以产生硬和软决策向量。通过伽罗瓦域算术计算综合征并找出两个最小值的位置。将这些值指定为LOW1和LOW2，并用Nc1指定，从而生成Nc2。将Nc1与Nc2交换并确定最低软判决值Min1和下一最低值Min2。创建Min1的两个位置被指定为MinA和MinB。 MinA被替换为Min2减去MinA值。 MinB被替换为Min2减去MinB的值。通过从所有其他位位置值中减去Min1来生成输出码字，并且2在其位置上用0互补所有软值。创建新的软值向量。

摘要： A hyper encoder module encodes a block of data having a plurality of sub-blocks. Each sub-block includes a plurality of systematic block code codewords. A parity sub-block is added to the block. The parity sub-block is a first sub-block rotated by a predetermined number of bits. Each subsequent sub-block in the n-dimensional block is rotated by an appropriate number of bits and bit-wise XORed. An encoder method and apparatus which includes the hyper encoder module receives the block of data. A row of the block is immediately output and encoded by a first module according to a first encoding scheme. A column is encoded by a second module according to a second encoding scheme. A second set of encoded data is generated, iteratively updated and output by the second module. The hyper encoder module hyper-diagonally encodes the information bits as described above and then output.
