Double Bits Error Correction Using CRC Method

Error during sending information due to devastating factors like external electromagnetic sources and noise is inevitable. The Cyclic Redundancy Check (CRC) method is used for error detection. CRC is used to control such factors in received information. In this paper, the new method based on CRC has been introduced that is able to detect the exact place of double bits error and correct them. In this method the receiver divide the received data on polynomial generator, g(x), and then get the remainder. Receiver can correct double bits error by comparing the remainder and the content of the look-up table. The result show that presented method can reduce the traffic for application that have low bit error rate (BER).
