  • Patent number: 9985661
    Abstract: Techniques for decoding potentially corrupted Reed-Solomon encoded messages are provided. To decode a message, an incoming message is classified into a group based on which symbols of the message have survived (a “survival pattern”). The same inversion matrix may be used for each survival pattern associated with a single group. This reduces the amount of work required and data that is to be stored in order to perform the matrix multiplication that decodes the message.
