Abstract  Abstract

A decoder for decoding a chain reaction code, with a plurality of output symbols (230, 720, 920) and a plurality of origin symbols (220, 710, 910, 1010), in which each output symbol is associated with one or more origin symbols, and the chain reaction codes being such that an origin symbol can be decoded from an output symbol of degree one, and the decoding of an origin symbol reduces the degrees of the output symbols that are associated with that decoded origin symbol, and the chain reaction code having a plurality of multi-stage output symbols and said plurality of origin symbols, each of the multi-stage output symbols already comprising it is said exit symbol or a check symbol, in which each of the multi-stage exit symbols is associated with one or more origin symbols, denominating the multi-stage exit symbols, associated with one or more origin symbols, multi-stage exit symbols of grade one or higher, in which at least one multi-stage exit symbol is associated with at least two origin symbols, denominating the multi-stage output symbols, associated with two or more origin symbols, multi-stage output symbols of degree two or higher, and in which at least one origin symbol is marked as active, the decoder comprising: ( 0) means for determining that no multi-stage exit symbol within the chain reaction code is associated with only one origin symbol, (i) means for selecting one of the active origin symbols associated with a multiple exit symbol stages of grade two or higher; (ii) means to deactivate the selected origin symbol, associated with a multi-stage exit symbol of degree two or higher, in which (ii) the means to deactivate the selected origin symbol produces a deactivated origin symbol and one or more recoverable origin symbols, in which each recoverable origin symbol is associated with a multi-stage output symbol of degree one, where the degree is determined as specified above, but considering the origin symbol deactivated as decoded; (iii) means to recover the values of one or more deactivated origin symbols; and (iv) means for determining, based on the values recovered from the deactivated origin symbols, the values of one or more recoverable origin symbols.
