Error Detection Based on Generator Polynomial

In today world use high speed computers.Communication between one computer and another orbetween the computer and its peripheral devices must beas error free as possible. However, error free datatransmission in real world communication systems doesnot exist. Errors, no matter how few, will always bepresent. To deal with this problem, a good number oferror detection techniques have been developed and usedextensively in data communication systems known as theCyclic Redundancy Check (CRC). In order toinvestigate the CRC error, handshake data (polynomialand handshake data bit) is sent to receiver subsequently,when the receiver accept the handshake, the polynomialis accepted by receiver. While in data communicationbetween sender and receiver, sender packed the data andpolynomial and then transmitted to receiver. When thepacket arrived to receiver, the received packet is dividedby polynomial. The receiver catches the result data
