摘要： Techniques are described for decoding a codeword. In one example, the techniques include obtaining a first message comprising reliability information corresponding to each bit in the first codeword, determining a plurality of least reliable bits in the first codeword, and generating a plurality of flipped messages by flipping one or more of the plurality of least reliable bits in the first codeword. A number of the plurality of least reliable bits is equal to a first parameter and a number of flipped bits in each of the plurality of flipped messages is less than or equal to a second parameter. The method further includes decoding one or more of the plurality of flipped messages using a hard decoder to generate one or more candidate codewords.

摘要： In staircase forward error correction coding, a stream of data symbols are mapped to data symbol positions in a sequence of two-dimensional symbol blocks Bi, a positive integer. Each of the symbol blocks has data symbol positions and coding symbol positions. Coding symbols for the coding symbol positions in each symbol block Bi in the sequence are computed. The coding symbols are computed such that, for each symbol block Bi that has a preceding symbol block Bi−1 and a subsequent symbol block Bi+1 in the sequence, symbols at symbol positions along one dimension of the preceding symbol block Bi−1, concatenated with the data symbols and the coding symbols along the other dimension in the symbol Bi, form a codeword of a FEC component code, and symbols at symbol positions along the one dimension of the symbol Bi, concatenated with the data symbols and the coding symbols along the other dimension in the subsequent symbol block Bi+1, form a codeword of the FEC component code. Thus, each row in [Bi−1T Bi] and each column in [ B i B i + 1 T ] , for example, is a valid codeword.

摘要： A digital broadcasting system and a data processing method are disclosed. A receiving system of the digital broadcasting system includes a receiving unit, an SI handler, and a decoding unit. The receiving unit receives broadcast signals including mobile service data and main service data. The mobile service data configure a data group, and the data group includes a signaling information region in some of a plurality of data regions. The signaling information region may include TPC signaling data and FIC signaling data. The SI handler acquires channel configuration information of the mobile service data from the broadcast signal using pre-decided IP access information, and extracts encoding format information for each IP stream component within a corresponding virtual channel service RTP-packetized and received from the acquired channel configuration information. The decoding unit decodes the mobile service data of the corresponding IP stream component based upon the extracted encoding format information.

摘要： Serially-concatenated codes are formed in accordance with the present invention using a constrained interleaver. The constrained interleaver cause the minimum distance of the serial concatenated code to increase above the minimum distance of the inner code alone by adding a constraint that forces some or all of the distance of the outer code onto the serially-concatenated code. This allows the serially-concatenated code to be jointly optimized in terms of both minimum distance and error coefficient to provide significant performance advantages. Constrained interleaving can be summarized in that it: 1) uses an outer code that is a block code or a non-recursive convolutional code, and as such, there are multiple codewords present in the constrained interleaver, 2) selects a desired MHD, 3) selects an interleaver size and a set of predefined interleaver constraints to prevent undesired (low-distance) error events so as to achieve the desired MHD, and 4) performs uniform interleaving among the allowable (non-constrained) positions, to thereby maximize or otherwise improve the interleaver gain subject to the constraints imposed to maintain the desired MHD.

摘要： Methods and systems for encoding and decoding data using a streaming product-code (SPC). An SPC codeword has a first and second portion in a first and second component stream of the SPC, respectively. The first portion of the first codeword is arranged along a first dimension of the SPC, and the second portion of the first codeword is arranged along a second dimension of the SPC. The SPC efficiently encodes data into a desired target frame format without the overhead of dedicated mapping logic used by product-codes solutions.
