Review on Detection of Error and Correction of Corrupted Code Using Fpga Implementation

Abstract

In this paper, the error detection and correction of the corrupted code is done by FPGA implementation using Xilinx and Modelsim software. In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. When data is stored, compressed, or communicated through a media such as cable or air, sources of noise and other parameters such as EMI, crosstalk, and distance can considerably affect the reliability of these data. Error detection and correction techniques are therefore required. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver. Error detection techniques allow detecting such errors, while error correction enables reconstruction of the original data in many cases. In coding theory ,hamming (7,4) is a linear error-correcting code that encodes four bits of data into seven bits by adding three parity bits.Hamming’s (7,4) algorithm can correct any single bit error ,or detect all single-bit and two-bit errors.
