NETWORK RE-ENCODING METHOD AND DEVICE FOR RE-ENCODING ENCODED SYMBOL TO BE TRANSMITTED TO COMMUNICATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a network re-encoding method and device of low complexity using rateless codes named LT (Luby Transform) codes.;SOLUTION: The network re-encoding device is intended for re-encoding encoded symbols to be transmitted to at least one communication equipment connected to a network. This network re-encoding device includes a re-encoding means arranged for re-encoding output nodes, defined by LT code symbols representative of encoded symbols and representative respectively of the results of XOR Boolean operation between input nodes defining decoded symbols whose values have to be discovered and to which they are linked into a Tanner graph, by combining chosen input node and/or output node having known values, in order to produce new LT code symbols defining generated output nodes ready to be transmitted.;COPYRIGHT: (C)2010,JPO&INPIT
