Error Detection and Correction Capability for BCH Encoder using VHDL

The BCH code is the essential class of multiple-error-correcting linear cyclic code. In actuality, Bose-Chaudhuri-Hocqunghem code is an abstraction of the cyclic hamming code for multiple-error correction. The finding of errors made by noise during transmission from the sender to the recipient is called as Error Detection. The finding of errors and renewal of the original data is called as Error Correction. The error can be detected and corrected for the fixed value of n and k. So that, the system efficiency and correcting capability are lower. In this paper, we are implementing a system in which we can detect and correct the flexible block length and message length. When the input data is applied to Galois field, the generator matrix H is performing the XOR operation with bits of the input register and formed the output.
