Survey on Error Control Coding Techniques
Abstract - Error Control Coding techniques used to ensure that the information received is correct and has not been corrupted, owing to the environmental defects and noises occurring during transmission or the data read operation from Memory. Environmental interference and physical effects defects in the communication medium can cause random bit errors during data transmission. While, data corruption means that the detection and correction of bytes by applying modern coding techniques. Error control coding divided into automatic repeat request (ARQ) and forward error correction (FEC).First of all, In ARQ, when the receiver detects an error in the receiver; it requests back the sender to retransmit the data. Second, FEC deals with system of adding redundant data in a message and also it can be recovered by a receiver even when a number of errors were introduce either during the process of data transmission, or on the storage. Therefore, error detection and correction of burst errors can be obtained by Reed-Solomon code. Moreover, the Low-Density Parity Check code furnishes outstanding performance that sparingly near to the Shannon limit.
