    摘要: The invention relates to a method dedicated to encoding data to be sent via a transmission infrastructure using waves, which includes: i) a step comprising simultaneously creating M first matrices with T rows and C columns with data subsets of B consecutive bursts received, the data subsets of each burst being distributed in at least two first consecutive matrices; ii) a step comprising simultaneously creating M second matrices with T rows and N columns with parity symbols resulting from encoding data respectively contained in the rows of each one of the M first matrices; iii) a step comprising simultaneously creating M third matrices with K rows and C columns with parity symbols resulting from encoding data respectively contained in the columns of each of the M first matrices; and iv) a step comprising distributing by interleaving J subsets of parity symbols of each second matrix in J consecutive sets, as well as P subsets of parity symbols of each third matrix in P of said consecutive sets, and placing the respective data of the consecutive bursts received in each one of the consecutive sets.

    摘要: A method of encoding data is described herein. According to the method, source data elements are coded using one or more product codes having a common component code. The resulting one or more primary product codewords consist of a plurality of first codewords of the common component code. One or more first sets of codewords of the common component code are assembled such that each of the first sets comprises two or more distinct first codewords forming part of a same primary product codeword. Each of the codewords of each of the first sets is codeword-mapped to a second codeword of the common component code using a one-to-one codeword-mapping. One or more second sets of second codewords are provided, where each second set corresponds to a first set of codewords. The codeword-mapping includes re-ordering, according to a known interleaving pattern, the symbols within a codeword. The codeword-mappings are such that if all of the codewords of a first set are from a same primary product codeword, then some codeword-mappings applied to the codewords of the first set are different, and if two or more repetitions of a same codeword are included in a single first set, then the codeword-mappings applied to those repetitions are different. Each set of second codewords is coded using a systematic code so as to generate a secondary product codeword for a product code having as component codes the common component code and the systematic code. Then, the primary product codewords and the non-systematic portion of the secondary product codewords are provided as encoded output data.

    摘要翻译: 这里描述了一种编码数据的方法。 根据该方法,使用具有公共分量代码的一个或多个产品代码对源数据元素进行编码。 所产生的一个或多个主要产品代码字由公共分量代码的多个第一代码字组成。 组合公共分量代码的一个或多个第一组代码字,使得每个第一组包括形成相同主要产品代码字的一部分的两个或多个不同的第一代码字。 第一组中的每一个的每个码字使用一对一码字映射码字映射到公共分量码的第二码字。 提供一个或多个第二组第二码字,其中每个第二组对应于第一组码字。 码字映射包括根据已知的交织模式重新排序码字内的符号。 码字映射使得如果第一集合的所有码字来自相同的主要产品码字,则应用于第一集合的码字的一些码字映射是不同的,并且如果相同码字的两次或更多次重复 被包括在单个第一集合中,则应用于这些重复的码字映射是不同的。 使用系统代码对每组第二码字进行编码,以便产生具有作为组件代码的公共分量代码和系统代码的乘积代码的次级乘积码字。 然后,作为编码输出数据提供副产品码字的主要产品码字和非系统部分。
