    • A communication system includes a first and a second communication devices, and the first and the second communication devices includes a first and a second transmission units that are disposed respectively on bodies of the communication devices and wirelessly transmits predetermined information to each other. The first communication device further includes a first reception unit that is disposed in a position where the first reception unit is capable of communicating with the second transmission unit and receives second information that has been transmitted from the second transmission unit, and a first control unit that controls the first communication device such that, when communication becomes possible between the first reception unit and the second transmission unit, the first reception unit receives the second information, and such that, when communication becomes possible between the first transmission unit and the second reception unit, the first transmission unit transmits first information.

    • In an LDPC-code decoder, bit-processing units are provided, respectively, for the 1st to Mth rows of the parity-check matrix that is formed of (r×s) permuted matrices having respective arrays of (m×m). Each of bit-processing units sequentially updates bit information corresponding to column positions included in the respective rows of the parity-check matrix, a bit at each of the column positions being set to “1”.Parity-processing units update parity information corresponding to row positions in columns of each column block of the parity-check matrix, whenever the bit-processing units have finished bit update computation for m column positions in each column block, a bit at each row position being set to “1”.The bit-processing units starts next bit update computation after the parity-processing units finish parity update computation for m columns of the first column block of the parity-check matrix.
    • 在LDPC码解码器中,针对由具有(m×m)的各自的阵列的(rxs)置换矩阵形成的奇偶校验矩阵的第1〜第M行分别提供比特处理单位。 每个位处理单元顺序地更新与奇偶校验矩阵的相应行中包括的列位置相对应的位信息,每个列位置处的位被设置为“1”。微处理单元更新对应于 每当位处理单元完成每列列中的m列位置的位更新计算时,每行位置的位被设置为“1”,位的位列位于奇偶校验矩阵的每个列块的列中 在奇偶校验处理单元完成奇偶校验矩阵的第一列块的m列的奇偶校验更新计算之后,处理单元开始下一位更新计算。
