摘要: A method of correcting errors in binary data comprises associating with each block of data words a plurality of check words for use in error detection and correction, each check word being derived in dependence on all the data words in the block and each other check word associated with the block. One check word may be derived by an exclusive-OR addition and the other or others may be derived using a primitive polynominal generator.
