Theory and practical tools to master matrix code design strategy and technique Correcting errors and detecting codes are very important to improve system reliability and have been popular have been applied to computer systems and communication systems. Coding theory has been studied mainly using the code generator polynomial, then, this code is sometimes called polynomial codes. As the author effectively shows, the code matrix is much more flexible than polynomial codes, since they are able to express different types of function codes. Unlike other publications coding theory, this one does not burden the reader with unnecessary polynomial algebra, but rather focus on the important things that needed to understand and take full advantage of matrix code constructions and designs. The reader is presented with a complete array of tools to master the theoretical and practical points of matrix code design strategy and technique: * The code design is presented in relation to practical applications, such as high-speed semiconductor memory, disk and tape mass memories, logic circuits and systems, data entry systems, and distributed storage systems * New classes of matrix codes, such as error location codes, spotty byte error control code, and error codes are not the same controls, introduced along with their application * A new parallel algorithm for decoding the burst error control codes is demonstrated Besides treatment of matrix codes, the author provides readers with an overview of the latest developments and advances in the field of design codes.
