The Implementation of Error Correction in ATM System

The researches on CRC mainly focus on error detection, seldom on the function of error correction. ATM is the core technology of B-ISDN which makes use of cyclic redundancy code to detect and correct the errors. ATM switching system generally adopts CRC to correct a single bit error in the cell header. Based on introducing the essential method of generating CRC, this paper analyses the process of correcting a single bit error in the cell header of the ATM system in detail.
