A Comparative Study between Hamming Code and Reed-Solomon Code in Byte Error Detection and Correction
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
This work concerns the comparative study between Hamming code and Reed-Solomon (RS) code in byte error detection and correction. Data are either stored in storage applications or transferred through a media. In either case there is problem of data corruption due to noise and interference, which has to be corrected as soon as they occur to prevent erroneous information throughout the system. The basis is to incorporate the original data with some form of redundancy. With this redundancy, even if errors are introduced, the original information can be recovered or at least the presence of error can be detected. Redundancy is added by the encoder and sent over the channel where noise in the form of error distorts the data. The message reaches the receiving end through the decoder where errors are removed, redundancy stripped off and the original message is then produced. This paper compared Hamming code and Reed-Solomon code in respect to their efficiency in adding and removing this redundancy. I find Reed-Solomon code to be highly efficient and more powerful than Hamming code for data communication because of it high coding rate and yet with a minimum coding complexity.
