摘要： A method for processing a chain reaction codes includes first selecting a source symbol which is associated an output symbol of degree two or higher (i.e., an output symbol which is itself associated with two or more input symbols), and subsequently deactivating the selected source symbol in an attempt to produce an output symbol of degree one. The inactivation process can be repeated either successively until an output symbol of degree one is identified, and/or whenever the decoding process is unable to locate an output symbol of degree one.

摘要： A method of encoding data for transmission from a source to a destination over a communications channel (145) is provided. The method operates on an ordered set of input symbols (205) and includes generating a plurality of redundant symbols from the input symbols (205). The method also includes generating a plurality of output symbols from a combined set of symbols including the input symbols and the redundant symbols, wherein the number of possible output symbols is much larger than the number of symbols in the combined set of symbols, wherein at least one output symbol is generated from more than one symbol in the combined set of symbols and from less than all of the symbols in the combined set of symbols, and such that the ordered set of input symbols (205) can be regenerated to a desired degree of accuracy from any predetermined number of the output symbols.

摘要： A communications system includes an encoder that produces a plurality of redundant symbols. For a given key, an output symbol is generated from a combined set of symbols including the input symbols and the redundant symbols. The output symbols are generally independent of each other, and an effectively unbounded number of output symbols (subject to the resolution of the key used) can be generated, if needed. The output symbols are information additive such that a received output symbol is likely to provide additional information for decoding even when many symbols are already received. The output symbols are such that a collection of received output symbols can provide probabilistic information to support error correction.; A decoder calculates check symbols from the output symbols received, wherein each check symbol is associated with one or more input symbols and redundant symbols For each received output symbol, the decoder updates a running total of 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 input symbols. This process may be repeated until, for all of the input symbols, one of the many possible values is much more probable than others, or the process may be repeated a predetermined number of rounds, or other criteria is met. The updating can take into account already decoded symbols, additional output symbols and the check symbols.
摘要翻译：通信系统包括产生多个冗余符号的编码器。对于给定的密钥，输出符号是从包括输入符号和冗余符号的组合符号集合中生成的。输出符号通常彼此独立，如果需要，可以生成有效无限数量的输出符号（取决于使用的密钥的分辨率）。输出符号是信息相加的，使得即使当已经接收到许多符号时，接收到的输出符号也可能提供用于解码的附加信息。输出符号使得接收到的输出符号的集合可以提供概率信息以支持纠错。解码器从接收到的输出符号中计算校验符号，其中每个校验符号与一个或多个输入符号和冗余符号相关联。对于每个接收到的输出符号，解码器更新估计的信息内容的运行总数，并且在一个或多个回合中，为输入符号的全部或部分可能值生成每个输入符号的概率分布。该过程可以重复进行，直到对于所有的输入符号，许多可能值中的一个可能值比其他值更可能，或者该过程可以重复预定数量的舍入，或者满足其他标准。更新可以考虑已经解码的符号，附加输出符号和检查符号。
