Error correction coding procedure for data transmission includes combined transmission of source and processed data following several stages of processing

摘要

The system provides coding which may be readily fitted into VSLI circuits. The procedure for error correction coding uses a data source series associated with a coded data block to be transmitted to at least one receiver. The procedure includes at least two coding stages (21i), each comprising at least two basic coding modules (22i,j). Each of the coding stages receives a series of data to be processed which is distributed between the basic coding modules, and delivers a series of processed data. There is also at least one branching stage (23i) inserted between two successive coding stages, distributing the processed data derived from each basic coding module of the first coding stage between at least two basic coding modules of the second stage. The resulting coded data block for transmission comprises at least a quantity of the source data, and a quantity of the processed data emerging from the last coding stage.
