Abstract  Abstract

The communication system includes an encoder for generating a plurality of redundant symbols. For a given key, an output symbol is generated from a synthesized symbol set that includes an input symbol and a redundant symbol. The output symbols are generally independent of each other and a virtually infinite number of output symbols (depending on the resolution of the key used) can be generated if necessary. Even when many symbols have already been received, the output symbols are information additives so that the received output symbols are likely to provide additional information for decoding. The output symbols are such that the set of received output symbols can provide probability information to support error correction. The decoder calculates a check symbol from the received output symbols, where each check symbol is associated with one or more input symbols and redundant symbols. For each received output symbol, the decoder updates the cumulative sum of the estimated information content and, in one or more rounds, generates a probability distribution for each input symbol over all or some of the possible values of the input symbol. This process can be repeated for all of the input symbols until one of the many possible values is much more likely than the other, or this process can be repeated for a predetermined number of rounds or until another criterion is met. have. The update may take into account already decoded symbols, additional output symbols and check symbols.
