    摘要： The invention relates to an electronic device (1) comprising a Bluetooth communication unit (2) configured to perform Bluetooth communication, this unit (2) including a memory module (10) containing a memory controller (11) and a memory element (12) equipped with at least one page (P) including at least one encoded data (E) consisting in a binary code being formed by a word (W 0-N) and its associated redundancy code (RC 0-N), the memory controller (11) being configured to store a user data in this page (P) by performing error correction code (ECC) calculations on this user data for providing an associated redundancy code (RC 0-N) corresponding to an erased redundancy code (RC E) for this user data, if this user data has a reference binary code of an erased word (W E), the said erased redundancy code (RC E) having a binary value similar to that of the reference binary code.

    摘要： In a coding device (20), a first coding unit (21) generates a parity of an RS code by coding, based on the RS code, each first data sequence existing in a direction different from a row direction of input data, and generates coded data by attaching the parity of the RS code to each first data sequence, thereby consequently expanding a matrix. A second coding unit (22) generates a parity of a BCH code and a parity of an LDPC code by coding, based on the BCH code and the LDPC code, each second data sequence existing in a row direction of the coded data, and generates a plurality of DVB-S2 frames (13) including, per DVB-S2 frame (13), one data sequence existing in the row direction of the coded data, the corresponding parity of the BCH code, and the corresponding parity of the LDPC code.

    摘要： The present technology relates to a transmission method and a reception device for securing favorable communication quality in data transmission using an LDPC code.
    In group-wise interleaving, the LDPC code with a code length N of 17280 bits is interleaved in units of 360-bit bit groups 0 to 47. In group-wise deinterleaving, a sequence of the LDPC code after group-wise interleaving is returned to an original sequence. The present technology can be applied, for example, in a case of performing data transmission using an LDPC code, and the like.

    摘要： The present technology relates to a transmission device, a transmission method, a reception device, and a reception method for securing good communication quality in data transmission using an LDPC code.
    LDPC coding for information bits with an information length K = N × r is performed on the basis of an extended parity check matrix having rows and columns extended by a predetermined puncture length L with respect to a parity check matrix of an LDPC code with a code length N of 69120 bits and a coding rate r of 14/16, so that an extended LDPC code having parity bits with a parity length M = N + L - K is generated. A head of the information bits of the extended LDPC code is punctured by L, so that a punctured LDPC code with the code length N of 69120 bits and the coding rate r is generated. The extended parity check matrix includes an A matrix of M1 rows and K columns expressed by a predetermined value M1 and the information length K = N × r, a B matrix of M1 rows and M1 columns, a Z matrix of M1 rows and N + L - K - M1 columns, a C matrix of N + L - K - M1 rows and K + M1 columns, and a D matrix of N + L - K - M1 rows and N + L - K - M1 columns. The present technology can be applied to data transmission and the like using an LDPC code.
