Abstract
Family of methods for correcting errors in transfer of information over a lossy medium. The message to be sent is first broken into Data Blocks, which are further divided into N data segments. These data segments are sent verbatim and followed by XOR combinations of the data segments, called Error Correcting Segments. Incorrect Data or Error Correcting Segments are detected through the use of a CRC or any other error detection algorithm, and errored Data or Error Correcting Segments are discarded. Once all Data or Error Correcting Segments for a message segment are received, logic or a look up table is used to determine which of the Data Segments can be recovered. The lost Data Segment recovery is done using a binary XOR of multiple good Data or Error Correcting Segments. For additional error correction, Data and Error Correcting Segments can also be repeatedly transmitted multiple times to further improve the performance of this algorithm.
