Cyclic Redundancy Codes: Study and Implementation

Abstract- This paper introduces a way to authenticate the data transmitted over the network using Cyclic Redundancy Check (CRC) error detection technique which work on the concept of binary division. A network must be capable of transmitting the data from one end to other end with accuracy. But transmission errors are the common fact of data communication. It is not mandatory that data received at receiver end is identical to the data transmitted by the sender. There are a number of reasons responsible for data corruption as thermal noise, impulse noise, etc. For reliable communication, it is required that the system must be enriched with error detection and error correction techniques. Therefore a number of error control techniques have been introduced and one of them is CRC to achieve accuracy in data communication. Index Terms- CRC (Cyclic Redundancy check), Data lin
