    • A parameterized interleaver design process is provided, which optimizes the design for interleavers of any size, and can be completely specified using only a few design parameters. According to the parameterized interleaver design process an interleaver π(i) of a length N is generated. A number of subpermutation masks are defined, and a first intermediate interleaver permutation is partitioned into a number of subgroups, wherein the number of subgroups corresponds with the number of subpermutation masks. Each of the subgroups of the first intermediate interleaver permutation is partitioned into a number of further subgroups, and each of the subpermutation masks is applied to each of the further subgroups of a corresponding subgroup of the first intermediate interleaver permutation, resulting in a corresponding portion of a second intermediate interleaver permutation. The resulting interleaver π(i) is generated based at least in part on the first and second intermediate interleaver permutations.
    • 提供了一种参数化的交织器设计过程,其优化了任何尺寸的交织器的设计,并且可以仅使用少量设计参数来完全指定。 根据参数化交织器设计处理,生成长度为N的交织器pi(i)。 定义了多个子鉴别掩码,并且将第一中间交织器置换分割成多个子组,其中子组的数量对应于子鉴别掩码的数量。 第一中间交织器置换的每个子组被划分成多个其他子组,并且每个子精确掩码被应用于第一中间交织器置换的对应子组的其他子组中的每一个,导致相应部分 第二中间交织器排列。 至少部分地基于第一和第二中间交织器排列来生成所产生的交织器pi(i)。

    • A wireless communication method implemented in a communication system includes receiving a first data sequence, and processing the first data sequence to obtain information containing at least one of a first number and a sampling spacing associated with the first data sequence. The method also includes permuting the first data sequence to generate a permuted second data sequence. Permuting the first data sequence includes determining a first parameter based on at least one of the first number and the sampling spacing, determining a second parameter based on at least one of the first parameter, the first number, and the sampling spacing, and determining a mapping relationship between a j-th data item of the permuted second data sequence and an i-th data item of the first data sequence. The method further includes outputting the permuted second data sequence.

    • An error correction device for reducing the amount of access to an external memory while preventing the capacity of an internal memory from increasing. An optical disc stores scramble data for each data block. A descramble circuit reads scramble data in the data blocks from the optical disc as read blocks and applies a predetermined scramble value to the scramble data of each read block to generate descramble data. A 1-shift calculator generates a first calculated value by shifting the scramble value by one byte using a generation polynomial. A second shift calculator generates a second calculated value by shifting the scramble value by a number of bytes corresponding to {(total bytes of the data block in the column direction)+1−(total bytes of each read block in the column direction)} using the generation polynomial. An EOR circuit generates descramble data by applying the first or second calculated value as the scramble value to the input scramble data.
    • 一种用于在防止内部存储器的容量增加的同时减少对外部存储器的访问量的纠错装置。 光盘存储每个数据块的加密数据。 解扰电路将来自光盘的数据块中的加扰数据读取为读取块,并将预定的扰频值应用于每个读取块的加扰数据,以产生解扰数据。 1移位计算器通过使用生成多项式将加扰值移位一个字节来生成第一计算值。 第二移位计算器通过将加扰值与{(列方向上的数据块的总字节)+ 1-(列方向上的每个读取块的总字节))对应的字节数移位来生成第二计算值} 使用生成多项式。 EOR电路通过将第一或第二计算值作为加扰值施加到输入加扰数据来产生解扰数据。
