Error Detection Based on Generator Polynomial

Abstract

In today world use high speed computers. Communication between one computer and another or between the computer and its peripheral devices must be as error free as possible. However, error free data transmission in real world communication systems does not exist. Errors, no matter how few, will always be present. To deal with this problem, a good number of error detection techniques have been developed and used extensively in data communication systems known as the Cyclic Redundancy Check (CRC). In order to investigate the CRC error, handshake data (polynomial and handshake data bit) is sent to receiver subsequently, when the receiver accept the handshake, the polynomial is accepted by receiver. While in data communication between sender and receiver, sender packed the data and polynomial and then transmitted to receiver. When the packet arrived to receiver, the received packet is divided by polynomial. The receiver catches the result data.
