New Decoding Algorithm for Double-Error-Correcting Binary BCH Codes
Fan Meng · Journal of Information Engineering University · 2002
A stepbystep decoding algorithm is introduced for doubleerror correcting binary BCH codes of length n=2m-1.The decoding algorithm can directly determine whether any received bit is correct or not without knowing the number of errors which occur in the received vector and also without determing the corresponding error location polynomial.The merit of the hardware decoder based on the algorithm is that it is very simple and also very fast.Besides,it is suitable for decoding long block codes.
