Method for encoding data with double-interlaced parity symbols, for a radio infrastructure, and associated codec

An encoding device for communication via a wave-based transmission infrastructure, the encoding device comprising:

• an encoding processor configured to create a first select quantity of first matrices in parallel, each first matrix with a second select quantity of rows and a third select quantity of columns, each first matrix with data subsets from successive received bursts, the data subsets from each burst being distributed among at least two successive first matrices, wherein the encoding processor is also configured to create the first select quantity of second matrices in parallel, each second matrix with the second select quantity of rows and a fourth select quantity of columns, each second matrix with parity symbols resulting from an encoding of the data respectively contained in the rows of each of the first matrices, wherein the encoding processor is also configured to create the first select quantity of third matrices in parallel, each third matrix with a fifth select quantity of rows and the third select quantity of columns, each third matrix with parity symbols resulting from an encoding of the data respectively contained in the columns of each of M the first matrices, and
• an interleaving processor configured to interleave subsets of parity symbols from each second matrix and subsets of parity symbols from each third matrix into successive sets, wherein the interleaving processor is also configured to place the respective data from the successive received bursts into each of said successive sets.

A method for encoding data to be transmitted via a wave-based transmission infrastructure, comprising:

• receiving successive data bursts originating from a content source;
• creating a set of first matrices, each first matrix formed by a first select quantity of rows and a second select quantity of columns, each first matrix including a subset of column data from each of two or more of the successive data bursts, the subsets of column data from each data burst being distributed over multiple first matrices in the set of first matrices;
• encoding data from the rows of each first matrix to form one or more row parity symbols for each row of each first matrix;
• creating a set of second matrices corresponding to the set of first matrices, each second matrix including the row parity symbols for the corresponding first matrix arranged in the first select quantity of rows for the corresponding first matrix, each second matrix including one or more columns in relation to the one or more row parity symbols encoded for the rows of the corresponding first matrix;
• encoding data from the columns of each first matrix to form one or more column parity symbols for each column of each first matrix;
• creating a set of third matrices corresponding to the set of first matrices, each third matrix including the column parity symbols for the corresponding first matrix arranged in the second select quantity of columns for the corresponding first matrix, each third matrix including one or more rows in relation to the one or more column parity symbols encoded for the columns of the corresponding first matrix;
• placing respective data from the received successive data bursts into successive encoded data sets;
• interleaving the row parity symbols from each second matrix into the successive encoded data sets;
• and
• interleaving the column parity symbols from each third matrix into the successive encoded data sets.
