ERROR DETECTION STRUCTURE AND METHOD USING PARTIAL POLYNOMIAL CHECK |
摘要 |
ERROR DETECTION STRUCTURE AND METHOD USING PARTIAL POLYNOMIAL CHECK Charles R. Erickson Philip M. Freidin The present invention provides a means and method of generating a long error checking polynomial remainder having the ability to detect errors with high reliability and inserting only a subset of the polynomial remainder periodically into a data stream, then at the receiving end recalculating the polynomial remainder and checking the inserted subset for errors. The polynomial has the property that the current remainder value is a function of all data previously transmitted in a transmission session. The subset transmitted also preferably has this property. A longer subset of the polynomial remainder, or the full polynomial remainder, may be inserted less frequently, and is preferably sent and tested at the end of the transmission session. |
