REVIEW ON DIFFERENT ERROR CORRECTION CODES

Data transfer between two or multiple nodes is a common but critical operation in many applications of communication network. When the data transfer through the communication network some error bit and noise is added with data. To obtain the original data at the receiver side Error Correction Codes are used. Communication performance is improved by enabling the transmitted signal to better withstand the effects of channel disabilities such as noise, interference and fading which occur during transmission as well as during comparison. In short the Error Correction is the detection of errors and reconstruction of the original, error free data. There are errors correcting codes to detect as well as correct errors. In this paper the detail review of error correction code techniques is done. The main aim of this paper is to study the different error correcting codes techniques available for the error correction during the transformation of the data from the communication channel in details.
