ABSTRACT

Cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks. A CRC-enabled device calculates a short, fixed-length binary sequence, known as the check value or CRC, for each block of data to be sent or stored and appends it to the data, forming a codeword. CRCs are based on the theory of cyclic error-correcting codes. The uses of systematic cyclic codes, which encode messages by adding a fixed-length, check value, for the purpose of error detection in communication networks. Cyclic Redundancy Check (CRC) plays a major role in data storage, communication systems and networking environment fields to detect errors. The speed of transmitting data with optimized design and algorithm utilization are the main challenges nowadays. This paper reviews about the error detecting and correcting code based on cyclic redundancy check.   

Keywords: Cyclic redundancy check, error detecting, correcting, block, data.
